We got below critical alert for F5. As checked /var is showing 84% used, but as per alert /var/named/lib has 1.92% free space left.
Please let me know, if there is any impact for this & how to free space for both /var & /var/named/lib.
Alert: CRITICAL - storage 32 (/var) has 1.92% free space left, storage 66 (/var/named/lib) has 1.92% free space left
Cli Alert: 011d004:3: Disk Partition /var has only 16% free
easiest at such a moment is open a ticket with F5 support, they can join a remote session and look at it with you.
if that isn't possible have a look at this article: https://support.f5.com/csp/article/K14403
it lists some common causes and a good command to dig into the use of a certain directory.
