The iSCSI RAID we have is about 26TB netto and I'm again faced with the question: How many partitions, which filesystem, which mount options etc.
My vote goes to XFS, if only one server needs acces to the LUN's; and GPFS (not GFS) if you need a cluster filesystem.
BR Bent (130 TB in one XFS installation, and 600 TB in one gpfs cluster)
For the User it would be the most simpel thing, to have one big filesystem she/he could fill with all the data and dont has to search e.g. on multiple volumes.
On the other hand, if one big filesystem crashes or has do be checked it will destroy a lot of data or the check will take hours ...
Any suggestions pro or cons are welcome! :-)
My favourite for now is 3 to 4 filesystems with the default ext4 settings. (Redhat EL 5.7, may be soon 6.1)
Thanks and best regards. Götz
