Ceph initialization script /etc/init.d/ceph was failing to start osd
when osd disk is already mounted and the umount fails because disk is
in use.
The script line has an umount command that fails if the partition is
in use. Then, the next mount command will fail returning 32.
If the error is that the partition is already mounted, look for
'already mounted on ${fs_path}' text in the output and then ignore
the mount error returning success and continuing the start script.
An example of error text output:
=== osd.0 ===
Mounting xfs on controller-0:/var/lib/ceph/osd/ceph-0
umount: /var/lib/ceph/osd/ceph-0: target is busy.
mount: /var/lib/ceph/osd/ceph-0: /dev/nvme2n1p1 already mounted
on /var/lib/ceph/osd/ceph-0.
failed: 'modprobe xfs ; egrep -q '^[^ ]+ /var/lib/ceph/osd/ceph-0 '
/proc/mounts && umount /var/lib/ceph/osd/ceph-0 ;
mount -t xfs -o rw,noatime,inode64,logbufs=8,logbsize=256k
/dev/disk/by-path/pci-0000:11:00.0-nvme-1-part1
/var/lib/ceph/osd/ceph-0'
Test-Plan:
PASS: Validate the new script with partition already mounted
on right location in AIO-SX and AIO-DX.
PASS: Validate the new script with partition already mounted
but on a different location in AIO-SX and AIO-DX.
PASS: Validate the new script with partition not mounted in
AIO-SX and AIO-DX.
