Error mounting drive from volume created on SAN

Posted on

Working with RHel7 server I've configured a new linear volume on our SAN. One already exists on our RHEL7 system, so I matched its configuration for the new drive.

While the new drive mounts and I can create files on it, I'm concerned that during startup I see 2 error messages:

TIMED: timed out waiting for device /dev-disk-by/x2dlabel-"mylabel".device
Dependency failed for /"linear volume nickname"

Again, I can cd to /myvolume, I'm just worried that since this is going to store a postgresql db that later on problems are going to arise.

I've created an entry for this mount point in /etc/fstab. Let's say that I entered LABEL=xyz. The original volume mounted from the SAN has ( for example) LABEL=abc. But if I enter the mount -a command I get this error:
Unable to find label xyz

Googling this I thought i might simply have to go in and enter:
tune2fs -Lxyz /dev/sdg but then I get an error message:
bad magic number in super-block while trying to open /dev/sdg

I know this is probably something simple that I'm missing. Hoping someone can point me in the right direction.

Thanks....
