Hi, Following the reports on ceph-users about damaged cephfs after updating to 12.2.6 I spun up a 1 node cluster to try the upgrade. I started with two OSDs on 12.2.5, wrote some data. Then I restarted the OSDs one by one while continuing to write to the cephfs mountpoint. Then I restarted the (single) MDS, and it is indeed damaged with a crc error: 2018-07-13 12:38:55.261379 osd.1 osd.1 137.138.62.86:6805/35320 2 : cluster [ERR] 2.15 full-object read crc 0xed77af7c != expected 0x1a1d319d on 2:aa448500:::500.00000000:head 2018-07-13 12:38:55.285994 osd.0 osd.0 137.138.62.86:6801/34755 2 : cluster [ERR] 2.13 full-object read crc 0xa73a97ef != expected 0x3e6fdb4a on 2:c91d4a1d:::mds0_inotable:head I think it goes without saying that nobody should upgrade a cephfs to 12.2.6 until this is understood. -- Dan _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
