Celerra /nbsnas/var/dump directory is full.
Hello all,
I have an older Celerra running 6.0.43-0 that is showing the /nbs/nas/var/dump directory is 100% full. When looking at the directory the lost+found file seems to be the issue. I have a few screen shots below.
Does anyone have any ideas on how to fix this issue? I am not really sure what the lost+found file is actually for in this directory. Any advice is appreciated.

what else is in that directory ? i find this directory contains kernel dump files if datamover happens to panic which can be safe to delete after they have been analyzed by EMC and copied over.

I am not able to list all the files in that directory. It shows that there is a total of 20, but only 2 show up.

can you su to root account and "ls -la" again ?
su root (not su - root)

dynamox, I'm having very similar issue on my NS-120. When I issue the "ls -la" using root, I see 2 directories, "lost+found" & "mgmtd".
I did have a bunch of old EMC Support log files that I deleted. I also deleted thousands of old alerts, but when I do "df -h" it still shows that my /nbsnas/var/dump" directory is 100% utilized. Any other thoughts?

check inside of /nbsnas/var/backup
this folder contains nas database backup files, there should be no more than a day or two worth of tar.gz files. If you see more talk to support, they should get cleaned up automatically.
Also check /nbsnas/var/emcsupport , if you see a bunch of old support_materials files, delete them.

Talk to EMC support – they have a list / knowledgebase article on what to clean up

Thanks for the quick response! When I go to that directory do a "ls -ltr", it says there are 38460 files/directories. It's displaying 18 .gz files though. Think I should call support?
I'm not a unix guy, so I'm a little confused why I'm only seeing 18 files, but it says "38460" total.

total is how many 1k blocks are in that directory (not recursive), to see more humanly readable output run ls -rtlh
so looks like that directory is fine if you only see 18 files. Did you check emcsupport directory ?

cd into /nbsnas/var/dump and run du -h
this should give break down by each subfolder, do you see which one is taking up a lot of space ?

The same. I had deleted those emcsupport files before posting in this thread so nothing else has changed. Within Unisphere, I'm still seeing an alert every hour that states the following:

I did delete a bunch of .zip files in the emcsupport directory. Using "ls -rtlh", I'm seeing total 15M & 1 .zip file.

Output:
16K ./lost+found
1.6G ./mgmtd
1.6G .
Looks like there is a 1.6GB file in mgmt called "core.13555"
