Tag: /tmp is 100% utilized

The host which created trouble for me was a local zone .Applicaton team reported login issue while connecting to the local zone.
When i checked swap utilization was 100% since application logs are writing on the /tmp FS.

df -h /tmp
Filesystem size used avail capacity Mounted on
swap 2.0G 1.9G 100M 100% /tmp

So i have logged in to the console of the local zone by using zloign -C “zonename” and deleted the files occupying /tmp and thus fixed the issue

root@myzone /root>zoneadm list -cv
ID NAME STATUS PATH BRAND IP
0 global running / native shared
1 zone1 running /zones/zone1 native shared
2 zone2 running /zones/zone2 native excl
root@myzone/root>zlogin -C zone1
[Connected to zone ‘zone1’ pts/2]
Last login: Thu Jan 1 06:03:35 from myzone

Take a deep breath

Identify the files which can be removed and run the rm or mv command against them.

root@zone1 /tmp>df -h .
Filesystem size used avail capacity Mounted on
swap 2.0G 216K 2.0G 1% /tmp
root@zone1 /tmp>

You can get the swap location reconfigured to avoid similar issues in future.
