I have a dm-cache device that throws the following error when I try to create it: device-mapper: cache: 253:20: unable to switch cache to write mode until repaired. device-mapper: cache: 253:20: switching cache to read-only mode device-mapper: table: 253:20: cache: Unable to get write access to metadata, please check/repair metadata. device-mapper: ioctl: error adding target to table How can I go about checking/repairing the metadata?
Hi I'm sorry but you've attached so little information there is no way to give you some useful hint. We need to know kernel version, OS (distribution), lvm2 version, version of cache_check tools and likely some more (dmesg/messages log) Also you need to attach 'dmsetup table' & 'dmsetup status' 'lsblk' You may get better results opening bugzilla at: https://bugzilla.redhat.com/enter_bug.cgi?product=LVM%20and%20device-mapper Regards Zdenek -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
