Help! I do not understand my swap output. We ran out of swap yesterday, and
I need to understand why the output we log didn't tell us the "real
picture".
We have an E4500 with 8GB RAM. I need to know exactly how much swap is
available. We only mount one disk slice as swap and it is 2GB in size, but
my swap output is very confusing. I am running Solaris 2.8
Entry in /etc/vfstab
/dev/dsk/c0t10d0s1 - - swap - no -
Format output:
Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 171 301.59MB (172/0/0) 617652
