32-bit File System Limits?

  • Running OMV 1.14 on my old workhorse Thecus N5200 unit that I retrofitted OMV on to, but it's running an old 32-bit only Celeron 600MHz processor. Now, before I go crazy and do something like buy 5x 6TB hard drives to upgrade it with, what file system limits are there on someone running the 32-bit build? I currently have 5x 1TB drives in RAID 5 and it works just great. Just wondering if there are any gotchas I should know about before looking at upgrading the storage?

  • OK, good to know. Have to dump ext4 going forward. So then between JFS and XFS, given my system's relatively low CPU power and 1GB of RAM that can be installed. Which one would be the better choice for making a 16TB+ volume? Or am I asking too much from this equipment really?

  • There is a limit on ext4 32 bit filesystem. 16TB

    Could someone verify wether or not EXT4 can be created as a 64bit filesystem on 32bit systems or if thats a no-no?

    Which one would be the better choice for making a 16TB+ volume?

    I'd go with XFS.

    Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

  • I created a raid 5 16tb array. Want to add another drive but looks like its 32 bit EXT4. Am I looking at this right? I am using 2.1.6 OM. Please help and forgive if i am ignorant. New to OM. Thanks.
