ReadyNAS Ultra 6 /dev/md0 is 100%

Hi All,

First time poster, long time follower :D

My NAS rebooted and started a resync and after some investigation and trolling through the posts, I have discovered /dev/md0 is 100%


Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/md0               4184756   4184756         0 100% /
tmpfs                       16         0        16   0% /USB
/dev/c/c             8736443516 8377719924 358723592  96% /c

I have looked at / where its supposed to be mounted and I come up to a total of 500mb


3.6M	bin
608K	dev
7.2M	etc
14M	frontview/
8.0K	home/
4.0K	initrd/
94M	lib
2.2M	lib64/
16K	lost+found/
4.0K	mnt/
4.9M	opt/
0	proc/
672K	ramfs/
40K	root/
5.1M	sbin/
0	sys/
3.1M	tmp/
0	USB/
248M	usr/
142M	var/
0     0
523M	total

I have excluded the link folders ( -> ) and "c"

The question is, where is the 4Gb odd being used up?

I can account for only 523 MB...

Any help would be appreciated...

So if I wait for the resync to finish, reboot, do some volume checks and if things are still strange, then do the os re-install, that would be a good plan?

I would suggest you make sure you have an up to date backup before doing any volume checks if you want to do one of those.

right.... So now would be a good time to get another NAS ;)

Also, by volume checks I mean the items under the volume maintenance tab, i.e. disk scrubbing and consistency checks

Ah

Still a good idea to make sure you have an up to date backup if you haven't backed up your data in a while.

I have the important stuff on a laptop ;)

But yeah, I need a new NAS for the rest of the data...

Any thoughts on the Fan readings on the health page?

That might be related to your OS partition getting full.

Would be interesting to hear if you still have the fan error after an OS Re-install.

Ok, I will wait for the resync and try a os re-install tomorrow.

Thanks again for all the help.
