Description:

Celerra Manager/Unisphere reporting file system capacity warning.

Error msg: dskMon[15087]: FS /dev/mapper/emc_vg_lun_5-emc_lv_nas_var_emcsupport mounted on /nbsnas/var/emcsupport filling up (at 91%, max = 90%)

Resolution:

Manually delete old support material files by logging into CLI over SSH by:
1. To verify the /nbsnas/var/emcsupport space usage:

$ df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/emc_vg_lun_5-emc_lv_nas_var_emcsupport 564416 483424 52320 91% /nbsnas/var/emcsupport

2. Change directory to /nbsnas/var/emcsupport and to check the list of support materials which contains useful information such as the exact size of the file, who owns the file and who has the right to look at it.

$ cd /nbsnas/var/emcsupport
$ ls -l
total 135264

3. Use the rm command to delete older support materials files to clean up the space.

$ rm support_materials_CKMxxxxxxxxxxx.xxxxxx_xxxx.zip

4. To verify the /nbsnas/var/emcsupport space usage:

$ df -kh
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/emc_vg_lun_5-emc_lv_nas_var_emcsupport 552M 123M 401M 19% /nbsnas/var/emcsupport

Permanent Fix:

Beginning with 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.
