XFS support unavailable?

[Shatter]

Hey, what happened to the support for the XFS file system?

root@bt:~# cat /proc/filesystems | grep xfs
root@bt:~#

I am having this problem as well. I googled for an answer and have found nothing. Does anyone have a workaround/solution?

Thanks

First off, there is absolutely not need to pipe cat through grep to do something that grep can do on its own.

root@bt:~# cat /proc/filesystems | grep xfs

Should be:

root@bt:~# grep -i 'xfs' /proc/filesystems

Now, what you should have done to check for NFS support:

pc-tesla jordan # grep -i xfs /boot/config-$(uname -r)
CONFIG_XFS_FS=m
CONFIG_XFS_QUOTA=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_XFS_RT=y
# CONFIG_XFS_DEBUG is not set
CONFIG_VXFS_FS=m

(Your results may be different as the above is not from the BT kernel.)

The above shows that XFS was compiled as a module. To get support for XFS we just need to load that module.

pc-tesla jordan # modprobe -l | grep -i xfs
/lib/modules/2.6.26-2-686-bigmem/kernel/fs/xfs/xfs.ko
/lib/modules/2.6.26-2-686-bigmem/kernel/fs/freevxfs/freevxfs.ko
pc-tesla jordan # modprobe xfs

Now we get:

pc-tesla jordan # grep -i xfs /proc/filesystems 
	xfs

No probs. I have since compiled a custom kernel with XFS support built in natively. The reason I asked for XFS support is because my password lists, WPA tables and rainbow tables are all stored on an external 500GB HDD using XFS.

(This is an old thread btw)

EDIT: I believe my /boot/config-2.6.30.5 (original BT kernel) shows that...
# CONFIG_XFS_FS is not set

See post number two then.

Eh, no sweat. I was merely surprised that this old thread was suddenly subject to activity.
Anyway, can you confirm that default BT kernel doesn't have XFS support built in neither natively nor as a module?

[gdselzer]

grep -i xfs /boot/config-$(uname -r)

returns:

# CONFIG_XFS_FS is not set
CONFIG_VXFS_FS=m

which leads me to believe that XFS was not included in the stock kernel (oversight or intentional?)

Short of recompiling a custom kernel, is there anyway to add XFS support? I am running BT4 off of a USB stick. I would have thought that XFS would be a standard part of any linux distro.

Thanks
