Can't mount filesystem

[Herdip Kalare_1]

I am attempting to mount a filesystem but get the following error

anaconda{root}# mount /dev/vg001/lv_runtime /tmp/herd_test/runtime
/dev/vg001/lv_runtime: unrecognized file system

As far as I can see the filesystem exists ?

Hi Herdip,

Did you just created the logical volume?. If so, did you run 'newfs' on it".

newfs -F vxfs /dev/vg001/rlv_runtime

If it was used before, don't run newfs as the data will be lost. Try different fs options.

mount -F vxfs /dev/vg001/lv_runtime /tmp/herd_test/runtime
mount -F hfs /dev/vg001.. etc

Hi,

Maybe the lv exist, but doesn't have a filesystem created on it. It may be used as a raw device for oracle / sybase database.

All this assuming there was no type mistake.

Hope this helps.

I'll assume that lv_runtime is a valid logical volume BLOCK device node and that your mountpoint exists and is a directory.
I'll also assume that you have created a valid filesystem on this LVOL. If any of these assumptions are incorrect then correct them. You probably need to specify the type of filesystem (e.g. -F vxfs) in your mount command because (probably) there is no entry for this thing in /etc/fstab or if you have an fstab entry is is badly formed.

Hello Herdip:


I think that you don't have any file system in this lvol.Please try this:

newfs -F vxfs /dev/vg001/lv_runtime
mount /dev/vg001/lv_runtime /tmp/herd_test/runtime

bye

Yes, just spotted my blindingly obvious error. I created the FS some time ago but am only jest getting around to using it and had not run the newfs command.

Thanks for your help.

"I created the FS some time ago but am only jest getting around to using it and had not run the newfs command."
This statement is self-contradictory. I assume that you meant "I created the LVOL some time ago."
