View Full Version : SLES 12 SAN LUN space increase !!

22-Feb-2016, 14:24
Dear ,

I have increased the space on LUN mapped to the server from SAN but even after re-scanning of LUNs and rebooting of the server it is not reflecting on the server !! :confused:

Any suggestions !!

Hi adym333,

since the size stays the same even after a server reboot, are you sure the SAN correctly exports the LUN?

Or is it that the *file system* on the server stays the same size? That's independent from the LUN size and would have to be adjusted separately.

hello adym,

please check with the commands fdisk -l, lsblk and multipath -l if the size of the LUN is recognized correctly

after that you will have to
- increase the size of the physical partition
- increase the size of the logical volume (if there is one)
- increase the size of the file system on the logical volume / physical partition

in this particular order.

Please be careful - especially when using logical volume management - because if you are doing it wrong you can destroy your whole data. So if possible, first make a full image or snapshot of your hard disks.
