I have a scenario where I have to use SAN storage for my Oracle Database installation single node production setup and need to keep Database configuration files on SAN. I am using Oracle VM manager to manage my Oracle Linux 7.5.
After attaching a SAN storage of capacity 1.2TB it was available & shown using 'fdisk -l' command. I have gone though different file systems viz ext2, ext3, ext4, xfs, ocfs2 etc and was little bit confused that time regarding which one should I use. However I have formatted the disk of 1.2TB using command 'mkfs.ext2 -b 4096 /dev/xvdc'. Everything is working fine and I am able to mount the disk /dev/xvc on my Linux Machine and have configured my database at SAN.
The question is whether it is fine to go with this file system i.e. ext2 in current production environment or should I plan to migrate it as ext3/ext4/xfs etc. If required then what could be the step wise process for migration?
