I just launched new EC2 instances with the Ubuntu precise and saucy AMIs. I installed
jfsutils, but I am unable to mount a JFS volume:
$ sudo mount -a mount: unknown filesystem type 'jfs'
/proc/filesystems it seems that neither JFS nor XFS are listed (nor BtrFS, for that matter). There doesn't seem to be any module to load:
$ sudo modprobe jfs FATAL: Module jfs not found.
It looks like the standard 'generic' kernel is installed:
$ uname -a Linux ip-10-0-0-209 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
What am I missing? Am I just stuck with ext3/4 on this machine?
JFS did work on the 10.04 EC2 AMIs.
