Hello,
I hope this is the correct mailing list.
I have btrfs running on a 6TB (5.5ish TiB) raid10 array on a 3ware
9750-4i controller. I decided to run a script and a got 5 checksum
errors for the same file (errors from dmesg below).
I deleted the file without any issues, reran scrub, and now I don't see
any errors. The file itself was unimportant as it was from a backup of
another box that I already have multiple backups of (and the box itself
is still fine). The disks in the array appear to all be fine and the
array is also healthy. I also run "verify" regularly. Verify appears to
be the controller's equivalent to scrub.
Additionally, according to smartctl, things are healthly although it
seems error logging isn't supported:
Vendor: LSI

Local Time is: Wed Aug 14 15:15:42 2013 PDT
Device supports SMART and is Disabled

SMART Health Status: OK
Error Counter logging not supported
Device does not support Self Test logging
Any idea what may have happened here? Is this something to worry about?
Thanks,
