I have an aws ec2 instance that's been running Ubuntu 12.04 for a good long while. It has attached to it an EBS volume formatted with xfs. Today after a reboot, I'm unable to mount this volume. After the reboot, it did not get automatically mounted as per /etc/fstab. Trying to manually mount it as below, I get the following:

mount -t auto /dev/xvdf /usr/local/mnt/media
mount: unknown filesystem type 'xfs'

So it appears Ubuntu has forgotten about xfs... Any hints or ideas as to what I can do to get this volume mounted would be really appreciated.

  • It looks like you've lost the xfs kernel module somehow. What kernel are you running — official or home-grown? Copy-paste the output of uname -a and of find /lib/modules -name xfs.ko. Jun 21 '14 at 10:05
  • I have the same problem; the xfs module is loaded and xfs is listed in /proc/filesystems.
