>> Can LVM cause these OOS? > Very unlikely. I have another idea here. I'll try to switch drive options for KVM from cache=none to cache=directsync or cache=writethrough. In that case KVM has to ensure that data is on disk. I suppose this means (with disk-flushes and disk-barrier disabled) that KVM will ensure data being written to DRBD layer and DRBD will ensure it is in RAID cache. Will come back with results in 2-3 weeks. Stanislav -------------- next part -------------- An HTML attachment was scrubbed...
