We recently purchased HP Lefthand 4500 G2 24TB box and also a DL380 G7 server. I'm running Centos 6.2 (RHEL 6.2).
The Lefthand box consist of 12 2TB HD's configured in RAID6. That gives me about 14.7TB usable space.
Scenario : iSCSI SAN for Fileserver at Advertising Agency.
Are there any recommendations / best practices on filesystem creation on iSCSI LUN's ? Regarding EXT4 or XFS? Write barriers, mkfs options on creating the filesystem ? Like, inode64, noatime etc....
XFS is preferred tho, as we will be hosting a large volume with >=1millions of files. My Plan is to create 6-8TB volume at the start.
As for now, the server and or Lefthand box is not connected to UPS, but will be real soon.
I have had really good experience with XFS over the last 10 years with large volumes but not so, if not at all any experience with EXT3/4 on large volumes.
Any recommendations and or help would be much appreciated.
Thanks allot. Best regards,
