Hello everybody,
I would like your opinion on the following question, why this happens in
centos and how to fix this (or a possible work around).
I have a drive with no partitions and formatted with xfs filesystem. I give
the drive a custom label "mydrive" and I mount it under
/dev/mountpnts/mydrive.
Then, I add a corresponding entry to fstab.
These, are the steps I followed,
mkfs.xfs -L mydrive -f /dev/sdf
mkdir /dev/mountpnts/mydrive
mount -L mydrive /dev/mountpnts/mydrive/
cat /etc/fstab,
LABEL=mydrive /dev/mountpnts/mydrive xfs
noatime,nodiratime,nobarrier,logbufs=8 0 0
These steps mount the drive under the mount point specified.
If I remove the drive and insert it back in after a while, the drive
doesn't mount, even though I have the required entry in fstab.
`mount -a` doesn't seem to work and provides me the following output,
mount: wrong fs type, bad option, bad superblock on /dev/sdj,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
If I restart my server, the drive gets mounted in the correct mount point
and works fine.
Can someone please shed some light on why a restart is required to re-mount
a drive and if there is way to mount the drive without a restart.
Thanks,
Raghuv Adhepalli.

I'd expect to see this as /dev/sdf1 (or 2 or 3 or whatever). I'm not certain you -HAVE- to do such a thing.. and if I were a better person I'd experiment with a VM... (which I may still do, but it's friday, I'm still at work and I'm ready to go home)
