What troubleshooting steps should I take if after completing a vgimportclone I see IO errors after mounting the imported disk?
Issue
-
After importing new disks with
vgimportcloneand then mounting those disks, running aduon the mounted directory produces IO errors. -
For example,
/dev/vg01/lvol0was imported withvgimportcloneto create/dev/vg01-2091/lvol0(note the -2091 in the volume group name). When/dev/vg01-2091/lvol0is mounted under/mnt/test-new, the mount returns no IO errors, but adu /mnt/test-newreturns IO errors.vmimportclonewas used in order to allow both the original and a copy of a block device to be mounted at the same time.
