I have a 1TB USB disk that I use for storage.
OS is Redhat 5.6
FS Type is ext3

I used Redhat's LVM to build the Logical volume, and all is normally well.

now my /dev/TSMVG/TSMLV is missing, and the LVM GUI shows /dev/sdc1 as an uninitialized entry.

I doubt anything is really "wrong" with the disk itself, and just want to get it to where I can mount it.

I plugged the disk into a CentOS laptop to verify that it functions - and ran fdisk just to print the partition table. It gave me:


Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 1 121602 976762583+ 8e Linux LVM



Where can I go from here? I really don't want to lose all the data.

Hi,

maybe mounting LVM or this will help you.

good luck

Does the LVM show up in any of the LVM tools scans? (vgscan, lvscan, lv/pv/vgdisplay etc)

If it doesn't show up in lvscan, since its on a USB device, you may need to manually activate the VG.

May activate the VG allowing you to mount it normally.

Unfortunately, i cant help with the LVM GUI, I have no experience with it.

Well I feel silly, but figured I would post my resolution.

I'm not command-line savvy on LVM for Linux. On AIX that's another issue, I'm mostly kung-fu-master over there.

I simply rebooted the server, making sure the USB disk was powered on prior.

That made sure LVM did the correct scan and built the special devices.

All is fine now.

I just need to learn more about Linux/LVM.
