How does this happen? A stressful write with compression? Rsync (with --inplace - can be stressful / lead to fragmentation on large files which change) + snapshot + remove old snapshot, for several remote sources (rsync server1, snapshot, remove old snap; rsync server2, snapshot, remove old snap etc.). Filesystem is RAID-1 with compress-force=zlib: /dev/sdc1 on /mnt/lxc2 type btrfs (rw,noatime,compress-force=zlib,space_cache) The last operation written to the logfile was snapshot removal. -- Tomasz Chmielewski http://www.sslrack.com -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
