It seems that it is always /dev/mapper/xpcvg-home that is corrupted after a crash. I'll try to attach another crash log Created attachment 180581 [details]
kernel log for another crash from today
This crash is deep inside the md code. So it looks like a software RAID bug. I would suggest that you send this report to dm-devel@redhat.com, since I don't believe the devicemapper / md developers use the kernel bugzilla. 4.2 is not affected. the bug was in raid456 and Neil Brown fixed it last summer; probably some 4.1 version is already ok. |
