Our local vendor built us a Supermicro/Adaptec system with 16x1TB SATA drives. We have a 12TB partition that they built as EXT2. When I tried to add journaling, it took forever, and then the system locked up. On reboot, the FS was still EXT2, and takes hours (even empty) to fsck. Based on the messages flying by I am also not confident fsck rally understands a filesystem this large.
Is the XFS module stable on 5.1 and 5.2? (The vendor installed 5.1 because that's what they have, but I ran "yum update"). Anyone have experience with filesystems this large on a Linux system? Will XFS work well for this? If any of you have successfully used EXT3 on a filesystem this large, are there any tuning tips you recommend? I was thinking of turning on dir_index, but somewhere I saw a warning this nmight not work with other OSes. Since we do have some Windows and Mac users accessing things via SMB, I wasn't sure that was safe. either. This is a 64bit system. 8^) Thanks, Miles
