Subject: 2 errors when scrubbing - but I don't know what they mean
Date: Thu, 28 Nov 2013 21:36:32 +0100 [thread overview]
Message-ID: <5297A950.3020100@informatik.uni-bonn.de> (raw)
Hello everyone,
when I scrubbed one of my btrfs volumes today, the result of the scrub was:
total bytes scrubbed: 1.27TB with 2 errors
error details: super=2
corrected errors: 0, uncorrectable errors: 0, unverified errors: 0
and dmesg said:
btrfs: bdev /dev/mapper/tray errs: wr 0, rd 0, flush 0, corrupt 0, gen 1
btrfs: bdev /dev/mapper/tray errs: wr 0, rd 0, flush 0, corrupt 0, gen 2
Can someone please enlighten me what these errors mean (especially the
"super" and "gen" values)? As an additional info: The drive is sometimes
used in a machine with kernel 3.11.6 and sometimes with 3.12.0, could
this swapping explain the problem somehow?
Best regards
Sebastian
