[SOLVED] system no longer knows about xfs filesystems?!?

djg1971 · 2011-11-21 20:51:57

last Monday (11/14/2011) my system was able to mount an external drive with an xfs filesystem on it.

as of today (11/21/2011) it no longer recognizes xfs:

% mount <my_dir>
mount: unknown filesystem type 'xfs'

does anyone else have this problem? i searched and didn't see anything in the forums.

Odd... I'm assuming that xfsprogs are installed? Is there anything of note in your dmesg or errors.log?

graysky: thanks for responding.

yes, xfsprogs is installed (xfsprogs 3.1.7-1 to be exact).

dmesg only says that it sees the disk just fine:

but I cannot mount it. when i try i get the error that xfs is an unknown file system type.

and no, there is nothing in errors.log or anyplace else i've checked.

it seems weird to me too...

Been a while since I messed with xfs. Try this:

# mount -t xfs /dev/sdxy /path/to/mountpoint

alphaniner · 2011-11-21 21:26:58

xfsprogs was updated sometime recently. I tried before and after the update though, and didn't have any problems.

djg1971 · 2011-11-21 21:38:46

graysky:

I tried issuing the command directly ("mount -t ........") also, before posting. The result is the same error - mount doesn't know about xfs.

alphaniner · 2011-11-21 21:47:03

First, run lsmod | grep xfs to see if the module is loaded. If you don't see something like

xfs                   742285  0

then run (as root) modprobe xfs .

If it doesn't return an error, try mounting again afterwards.

alphaniner:

That I didn't try. The result is not good:

"FATAL: Module xfs not found."

I must have all the necessary packages installed as this was working when I went out of town last Monday night. Any idea where to go from here?

alphaniner · 2011-11-21 21:52:38

Are you using a custom kernel or something? For me, the xfs module came with the kernel package (linux):

$ pacman -Ql |grep xfs.ko.gz
linux /lib/modules/3.1.1-1-ARCH/kernel/fs/xfs/xfs.ko.gz

djg1971 · 2011-11-21 21:58:46

No custom kernel. Here is the output from the command:

[root@xxxxx log]# pacman -Ql |grep xfs.ko.gz
linux /lib/modules/3.1.1-1-ARCH/kernel/fs/xfs/xfs.ko.gz

patroclo7 · 2011-11-21 22:06:10

Reboot, you probably upgraded to a more recent kernel, so that the kernel you are using does not find the newer modules

mcmillan · 2011-11-21 22:07:27

Agree with patroclo, that seems the likely explanation. uname -r should give you

3.1.1-1-ARCH

If not you are running a different kernel than what's currently installed

djg1971 · 2011-11-21 22:24:08

okay ... i'm officially embarrassed. I was extremely busy this morning after returning from a field experiment and forgot that the kernel was updated during the system upgrade I did, so had not rebooted. I am indeed using the latest kernel, and rebooting did indeed solve the problem. Thanks, and sorry for wasting your time to everyone who tried to help.

Hi. Don't be embarrassed. I got the same problem, but with iso 9660. This thread just saved me some time I'm going to reboot right now.
