(after app prompt)
Now, DO NOT start your work yet. This is your last chance to ask any question (for both input sample and future possible input). Make sure you fully understand my question. say "Okay" if you are ready for input, say your question if any (so I will update this prompt).
After that, you will simply give output. No more question allowed.
You are an "AI function", which accepts input and prints output in specific format. Your task is:
Given some food, you need to search your knowledge base (or Internet) and tell me, for each food, how long could it be safely stored in room temp, refrigerated, and frozen condition.
You need to output a csv, each row is a food (as input), each column is a condition (room temp, refrig, frozen). In each cell, tell how long could it be safely stored.
Output Detail:
The output time should be in minimal format. Example: "7d" means 7 days, "2m" means 2 months, "1y" means 1 year.
If this food should not be stored in this condition at all, just put "NA". For example, potato should not be refrigerated, ice cream should not be in room temp, tomato should not be frozen. Just say "NA".
If food quality would be so badly affected after frozen (for example, green onion / most fruits tastes bad after frozen), you should also say NA. (you should determine how much is "so badly")
(My example could be incorrect but I hope you got my idea)
Input Example:
red potato, ice cream, tomato, raw eggs, watermelon, cherry, green onion, onions, roasted peanuts
Output Example:
Food,Room Temp,Refrig,Frozen
FoodA,1d,7d,1m
FoodB,10d,2m,NA
You can only output CSV. No more question allowed.
You have done a great job so far. Now I have a new task for you:
I am a software developer, managing my own blog website and other Internet services, so I have a lot of emails from various merchants, VPS sellers, cloud service providers, and other email from my daily life.
There are many notifications, such as service event notification, billing notification, payment notification, delivery notification, and so on. Some of them are very useful to me, because it contains something serious, I should pay attention.
But other notifications, telling me "your statement is ready" without sending the statement itself, it's useless and I will be annoyed. I'm angry if someone tells me to "pick up my statement from their website by myself". Please rule them out.
Some notifications suggests me to "stay secure" or "take required security action". I hate these emails about teaching me how to do my job. I am a good software engineer, and I know how to keep secure. Please rule them out unless they are especially targetting information security specialists (such as new 0-day exploits with a CVE number).
Some tells you about new feature, new product, discount, promotion, and so much boring things. I hate these email so much.
Note that, if the same merchants send me a lot of similar email repeatly, I will also be annoyed.
I'm a first-gen immigrant to the US, so immigrant-related email would be important to me.
For Notifications: duplicate notification (such as 'Order Shipped' if there is already an 'Order Confirmed' email) has much lower importance.
Your task is:
I will give you some texts from email, and you need to predict if I will be interested into it, and predict if I should pay attention to it. I would request you to also give exactly one "tag" for its category. Additionally, For every email, please give me a score (ranged from 0 to 100) representing the "usefulness" of the email.
Available tags: Notification, Marketing, Important (Example: Flight e-ticket, police message, or immigration info), Useful_Once (OTP or boarding notification, only useful in the next few minutes), Service_Incident, Friend (watch for tone/topic. many marketing/spammer pretend to be your friend!), Scam_or_Spam (including Marketing from scammers, watch for suspicious sender/text), Other
If the tag is "Notification", I would be interested into the score. For other category, you don't need to give a score.
Output format should be similar to ini:
tag=Notification
score=60
Thanks!

It's Dec 2024, I know btrfs is much more stable and mature. I'm using openzfs for my NAS, and I have some questions. I want to know of btrfs is able to meet my needs (I will talk to you about how I currently use ZFS)
ChatGPT said:
Sure, share how you currently use ZFS and your specific needs. I'll let you know if Btrfs can meet them.
You said:
Firstly, I need the filesystem to do active checksum check, to make sure if the file is broken or check if drive is failing.
ChatGPT said:
Btrfs supports active checksum checking for data and metadata. It uses CRC32C for this purpose. If data corruption is detected, Btrfs attempts to repair it using redundant copies, provided the volume has redundancy (e.g., RAID1, RAID10).
However, unlike ZFS, Btrfs does not perform regular scrubs by default; you need to schedule them manually or via a cron job. Would this meet your requirements?
You said:
okay it's good if I can initiate scrub with a easy command.
ChatGPT said:
Yes, initiating a scrub in Btrfs is straightforward. You can start it with:
btrfs scrub start /mountpoint
You can also monitor the progress with:
btrfs scrub status /mountpoint
And stop it if needed:
btrfs scrub cancel /mountpoint
This makes managing scrubs quite easy. Let me know what else you'd like to know!
You said:
I'm using ZFS with different layer of SSD. I have two 2T-SSD form RAID1, two 4T-SSD form RAID1, and these two RAID1 forms a RAID0. Could I do this in btrfs?NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT

ChatGPT said:
In Btrfs, you can achieve a similar setup with nested RAID configurations, but it has limitations compared to ZFS for complex layouts. Here's what you can do and some considerations:
Setup in Btrfs:
RAID1 for each SSD pair:
Create a RAID1 for each pair of SSDs:
mkfs.btrfs -m raid1 -d raid1 /dev/sdX /dev/sdY
RAID0 across the RAID1 volumes:
Btrfs cannot natively combine RAID1 pools into a higher-level RAID0 directly. You can achieve this by using a union filesystem (e.g., mhddfs, mergerfs) or by manually managing files across RAID1 volumes.
Challenges:
Nested RAID Levels: Btrfs does not support multi-level RAID like ZFS. While it supports RAID0, RAID1, RAID10, and other configurations, nested RAID setups like your ZFS configuration are not natively supported.
RAID Performance Balancing: Combining different capacities in RAID0 with Btrfs is possible but may lead to imbalances in performance and space utilization, as Btrfs handles mixed device sizes differently compared to ZFS.
If this setup is crucial, sticking with ZFS or exploring DMRAID (Device Mapper RAID) with Btrfs for RAID handling might be better. Let me know if you'd like guidance on specific commands or alternatives.
You said:
okay I simply have some SSDs with different capacity. I want to avoid wasting them, using them to form a reliable as-big-as-possible storage pool. Could I add different capacity into some btrfs pool with redundency? (I don't need you to tell me configuration. I just need a brief design, like which RAID solution do you recommend?)
ChatGPT said:
For a setup with different SSD capacities while maximizing storage and maintaining redundancy, Btrfs provides a flexible solution using RAID1c3 or RAID1c4. Here’s a brief design:
Btrfs RAID1 (Chunk-Based Redundancy):
Unlike traditional RAID1, Btrfs allows you to use drives of differing sizes efficiently.
Data is mirrored across devices, ensuring redundancy, but Btrfs does not require identical-sized disks. The filesystem manages chunks and mirrors them dynamically.
Recommendation:
Use RAID1c3 (3-way mirroring) or RAID1c4 (4-way mirroring) for greater fault tolerance, especially with more devices.
Btrfs will distribute data such that the redundancy is maintained without wasting excessive capacity.
Expected Outcome:
You will achieve redundancy similar to RAID1 but without the strict capacity-matching requirements. This approach makes the most of your differently-sized SSDs.
Let me know if you’d like further details about implementing or estimating usable capacity!
You said:
with 2x2T, 2x4T SSDs, I want at least 6TB resulting storage pool, and be safe with at least 1 drive failure.
ChatGPT said:
To achieve a 6TB+ storage pool with at least 1-drive redundancy using your 2x2TB and 2x4TB SSDs, the best configuration in Btrfs is RAID10. Here's why:
RAID10 Explanation:
Combines RAID1 (mirroring) and RAID0 (striping).
Data is mirrored across pairs, ensuring redundancy, while striping improves performance.
Btrfs optimizes space usage even with mixed-capacity drives.
Usable Capacity Calculation:
Btrfs RAID10 dynamically balances data, avoiding wasted space where possible. With your 2x2TB and 2x4TB setup, you'll achieve approximately 6TB usable capacity:
Mirroring ensures redundancy: the larger drives (4TB) will partially pair with smaller drives (2TB).
Remaining space on larger drives may not be used due to mirroring constraints.
Redundancy:
RAID10 in Btrfs tolerates the failure of any one drive without data loss. If two drives fail, they must not be from the same mirrored pair for data to remain intact.
This design fits your requirements. If you want to explore other solutions (e.g., RAID5 or RAID6), note that they might slightly increase usable space but could have trade-offs in reliability or performance. Let me know if you'd like details on those.
You said:
okay. Thirdly,
ChatGPT said:
Go ahead with your third requirement!
You said:
thirdly, there is a useful command "zpool status". I have a script to check output of this command, and it tells me if the pool is very healthy, or needs drive replacement.
ChatGPT said:
In Btrfs, the equivalent of zpool status is the command:
btrfs device stats /mountpoint
This will show you:
Read, write, and checksum errors for each device in the filesystem.
A quick summary of drive health.
Monitoring Health:
To check detailed filesystem health, use:
btrfs scrub status /mountpoint
This provides information about data corruption and repair status.
For drive-specific health checks, integrate with tools like smartctl (from smartmontools) to monitor the physical condition of drives.
Your script can be adapted to parse the output of btrfs device stats and btrfs scrub status for automation. Let me know if you need help transitioning your script!
You said:
nice. and fourthly, I need snapshot feature. I know btrfs supports snapshot in day-1, but zfs can do snapshot super easily: zfs snapshot nas-data-raid@ann20241001-1151 like this. And zfs can list snapshot easily: zfs list -t snapshot, and mount snapshot easily (just make it visible). Is btrfs also easy to do snapshot?
ChatGPT said:
Yes, Btrfs provides robust and easy-to-use snapshot functionality. Here's how it compares to your ZFS workflow:
Creating Snapshots:
Use btrfs subvolume snapshot:
btrfs subvolume snapshot /mountpoint /mountpoint/.snapshots/ann20241001-1151
This creates a read-write snapshot. Add the -r flag for a read-only snapshot:
btrfs subvolume snapshot -r /mountpoint /mountpoint/.snapshots/ann20241001-1151
Listing Snapshots:
Snapshots are simply subvolumes, and you can list them with:
btrfs subvolume list /mountpoint
You can add filters in scripts to identify specific snapshots by naming convention.
Accessing (Mounting) Snapshots:
Snapshots are immediately accessible under their creation path. No additional mount steps are required if they’re stored in the visible filesystem hierarchy.
Cleanup:
Delete snapshots with:
btrfs subvolume delete /mountpoint/.snapshots/ann20241001-1151
Btrfs snapshots are lightweight and easy to manage, comparable to ZFS. If you’d like example scripts for automation, let me know!
You said:
Could you give me a summary of all my questions (all my needs) mentioned above? So I can make a list & keep in mind. Thanks
ChatGPT said:
Certainly! Here's a summary of your requirements and how Btrfs can meet them:
1. Active Checksum Checking for Data Integrity & Drive Health
Btrfs supports active checksum checking for both data and metadata using CRC32C.
You can manually initiate scrubs to check for errors and correct them if redundancy is configured (RAID1, RAID10, etc.).
Scrub command: btrfs scrub start /mountpoint
2. Handling SSDs of Different Capacities with Redundancy
Btrfs can support mixed-capacity drives in a redundant setup.
RAID10 is the most suitable for combining your 2x2TB and 2x4TB SSDs with redundancy, providing about 6TB of usable space while allowing for 1 drive failure without data loss.
3. Health Monitoring and Drive Status
Use btrfs device stats /mountpoint to monitor health, similar to zpool status.
Scrub status can be checked with btrfs scrub status /mountpoint.
For more detailed drive health, you can use smartctl (from smartmontools).
4. Snapshot Functionality
Btrfs supports easy snapshot creation:
Create snapshots: btrfs subvolume snapshot /mountpoint /mountpoint/.snapshots/ann20241001-1151
For read-only snapshots, use: btrfs subvolume snapshot -r /mountpoint /mountpoint/.snapshots/ann20241001-1151
List snapshots: btrfs subvolume list /mountpoint
Delete snapshots: btrfs subvolume delete /mountpoint/.snapshots/ann20241001-1151
Snapshots are lightweight, fast, and mounted automatically under their directory path.
This list should serve as a good reference for setting up and managing your Btrfs storage system. Let me know if you need further clarification!
