Cache RAID1 BTRFS SSD - write errors

9 posts in this topic Last Reply

Recommended Posts

Randomly got write errors - seems to be I/O related. Wasn't doing anything unusual. Any way to diagnose the cause? Also, would you recommend RMA-ing the drive?

 

Running 6.8.0rc7

 

Thanks!

Update: things seem OK after reboot. Cache drives mount and no errors so far. Should I backup and reformat the cache? (i.e. if filesystem has been corrupted?)

 

[edit] Ran a btrfs scrub on /mnt/cache. No errors

One of the cache devices (cache1) previously dropped offline:

 

Nov 23 20:05:04 Tower kernel: BTRFS info (device dm-11): bdev /dev/mapper/sdl1 errs: wr 24, rd 0, flush 0, corrupt 0, gen 0
Nov 23 20:05:05 Tower kernel: BTRFS info (device dm-11): enabling ssd optimizations

 

Possibly because of that there is some corruption on the filesystem, it will likely happen again, I would recommend re-formatting the pool, also see here for better pool monitoring.

Thanks - I will re-format. And I just began running your script. To make sure I understand, why do you think the device dropped offline as opposed to something else causing the previous write errors?

Also, I ran a BTRFS scrub on /mnt/cache without any errors - does that rule out corruption? Would prefer skipping re-format if possible

Write errors to an SSD usually means it dropped offline, but without the syslog can never say for sure.

Scrub only checks the data, it doesn't check files system consistency, you can leave it as is for now and see if it doesn't happen again, just make sure backups are current.

 

You can also run btrfs check --readonly, but if errors are detected best to format instead of trying to fix them, btrfs fsck is still very fragile, and can even make things worse when trying to fix a corrupt file system.

Does this speak to wear and tear on the SSD hardware, unavoidable nuissance with all SSDs, or is it cabling? Wonder why this happens more with SSDs

I wouldn't say it happens more with SSDs, just that read/write errors with SSDs are most likely a connection problem, with HDDs sometimes there are actual bad sectors.

Gotcha. Will replace the cable just in case
