Large LV, expereinces and recommendations?

10TB is fine - we format the disks to xsf when you create the volume group. If iSCSI LV is created then the OS's will do the rest.

This may be out of date now, but from a previous nightmare we had with DSS, make sure you are running in 64bit mode and have lots of Ram, otherwise fsck etc. can never complete a scan on a large volume! Cheers.

Hi Tymish

The more ram that you have the faster FSCK will run,
Just remember to run a memory test before fsck.
FSCK will move data from disk to ram to fix it
if you have bad ram it will corrupt your data


as for volume size, you can always expand the LV size but you cannot shrink a LV.
MAy be better to start with smaller LV and then expand them as you need to.
