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 !! 😕

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.

Regards,  
Jens

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.
