somethings filling up but what?
Hi
I get an error every hour, and ignoring it hasnt made it go away! if anybody could explain what it is and how I can get rid of it it I would be grateful..
| Severity: | |
| Brief Description: | dskMon[20744]: FS /dev/mapper/emc_vg_lun_0-emc_lv_nas_var_dump mounted on /nbsnas/var/dump filling up (at 100%, max = 90%). |
| Full Description: | The feature identifed has detected a potential capacity issue that may need the attention of the system administrator. The device name and mount point is indicated in the event posting. |
| Recommended Action: | Check that the mount points condition is in fact approaching cautionary levels. Use normal administrative procedures to see if some free space can be returned to the mount point, such as removing unnecessary files or reorganizing areas of this mount point off onto other less full mount points on the sytsem. If no means are available to reduce the space consumptoin on this mount point then you may want to investigate if there is a possibility that this mount point needs to be expanded to allow for more free space. Contact your Authorized Service Provide if you need assistance with this process or need to discuss acquiring additional storage system capacity. |

In /nbsnas/var/dump you can delete the oldest file beginning with "support_materials" by opening a putty session to the control station and cd /nbsnas/var/dump, issue an ls -l command to perform a long listing of the files in that directory where you will see the dates on the support_materials files.
You can delete the older support_materials files. I would expect this to stop the alerts.
When upgrading to 6.0, and if the directory is still full, the pre-upgrade check process may flag this as needing attention prior to performing the upgrade.
So either way you benefit from the clean up.
If you have any reservations about the file deletion, please open a service request with EMC Support and we would be more than happy to assist in resolving this for you.

Hi JGreen, thanks for replying to this, the software version is 5.6.46-46. I'm not sure what I can or can't delete, I'm hoping to go to 6.0 in the next couple of weeks, so if you're right this will solve my problem, or do you recomend deleting the support materials prior to this? which directory are they in? how can I see which is the oldest, and what is safe to delete?

Workaround:
Manually delete some old support materials files to clean up the space. The alert will be eliminated.
Fix:
NAS code 5.6.50.x has a fix that will detect when the partition is more than 90% full and remove the oldest support materials.

Core dump files would have been next in the discussion.
Glad you were able to resolve.
Have a nice day.

Hi there.
Good post. Can I get details in the core dump files. I have the /nbsnas/var/dump at 91% and there's no supportmaterials to delete:
[nasadmin@SRVPRSGRCS01 dump]$ ls -ltr
total 1432472
drwx------ 2 root root 16384 Dec 14 2010 lost+found
-rw-r--r-- 1 nasadmin nasadmin 2110299 Jan 27 2011 mgmtd_core.10157.gz
drwxr-xr-x 2 root root 4096 Jan 27 2011 mgmtd
-rw-rw-r-- 1 nasadmin nasadmin 4683 Oct 3 18:17 header_CK200105000562.111003_1817.txt
-rw-rw-r-- 1 nasadmin nasadmin 1463268059 Oct 3 18:22 dump_CK200105000562.111003_1817.dump.gz
Can I delete/transfer the dump_CK200105000562.111003_1817.dump.gz to another place?

How can I transfer this file away from the Celerra? I can't send it to another host because I don't have that much free space anywhere. Is there a way to grab it to my own PC?

Yes. Make sure your support representative has obtained a copy of the dump before deleting. It is invaluable in determining the cause of your panic.

The dump must be from yesterday. We had a panic in the active datamover and the dump was generated, but it's quite large. Shouldn't I keep it for analisys?
