After adding a second dm device to a server and rebooting,
the server reports that /dev/sdd has failed fsck check. Once booted after
continuing dmsetup reports a linear device for /dev/sdd. It also reports it for
multipath. Once I remove the linear device I can mount the partition and
everything appears fine. While researching this problem I found that I
was creating the partition on dm device incorrectly, by fdisking /dev/dm-x.
This is the only one that has this issue. It is also the first multipath device
connected to our new IBM san.
I have tried removing multipath –f svnbackup and then
running a manual fdisk on /dev/sdd. (inactive path)
fdisk /dev/sdd
Unable to read /dev/sdd
Checking /dev/sdb reports everything is fine. This make
since to me because this is the active path and sdd failed and is inactive.
When I run multipath after checking everything it recreates
the linear path svnbackup1 along with the multipath. I am not sure why this is
happening.
Attached below are the output for dmsetup and mutlitpath –v3
Please let me know if you need any additional info.
Thanks,
Keith.
