Hi! I have Leap 42.2 as KVM host with clients also running Leap 42.2 On the host I use LVM and prepare logical partition (create the, format them and populate them with data). Then I assign these logical partitions the clients as block devices (on the host the partition is not mounted any more after assignment). Using ext4, this setup works well. Using btrfs on the LVM partition works only for a few days. Then I get corrupted btrfs filesystems (cannot mount any more) with error like these: Jun 03 17:33:03 test kernel: BTRFS error (device dm-11): parent transid verify failed on 205856768 wanted 4412 found 4418 Jun 03 17:33:03 test kernel: BTRFS error (device dm-11): parent transid verify failed on 205856768 wanted 4412 found 4418 Jun 03 17:33:04 test kernel: BTRFS error (device dm-11): open_ctree failed S.M.A.R.T. shows no problems. Anyone else having this problems? I know that btrfs requires trimming, scrubbing and balancing which is done on Leap 42.2 as a cronjob. Might these cronjobs on the host interfere with the partition mounted inside the client? best regards Thomas -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
