Hi Vincent,
Could you please provide?
1) any lvm config file or other "stacked" block device configurations runtime- config. log
2) if lvm: vgscan -vvv 2>&1 | tee > vgscan.log
3) multipath.conf
4) echo 'show config' | multipathd -k > multipathd-
5) dmsetup table -v > dmsetup.log
6) multipath -v4 -ll > multipath.log
7) system logs
put that together into a tarball with a datetime stamp and attach it to the bug.
To assist in debugging. Please stop multipathd, flush all paths and then only
run multipath client so we can observe how the paths are created.
0) service multipath-tools stop create- all-no- daemon. log no-daemon. log normal- listing. log
1) multipath -F # check that paths have been deleted
2) multipath -v4 > multipath-
3) dmsetup table -v > dmsetup-
3) multipath -ll > multipath-
attach all this in another tarball appropriately labelled and attach.
BTW, is your hardware handler actually installed? lsmod | grep scsi_dh
Help me understand why your SD names have 'lapped" to use an additional character,
are you performing a lot of hotplug or are there that many disks? an lsscsi -l output
would be nice.
Thanks.
