Yes Sol 10 is a UFS file system. It uses logging which is pretty similar to journaling in ext3.

Thanks guys for all the input. The Sol 10 server's running Oracle 10g RAC and doing alot of core dumps into /var. Thing I'm yet to figure out is what the previous output means exactly.
Filesystem size used avail capacity Mounted on ... /dev/md/dsk/d30 9.6G 8192E 0K 92365229983016% /var ...
Especially the values:
used => 8192E avail => 0K capacity => 92365229983016% - Though I think Ashok is right, 16% is the capacity used in the partition...(1.7G/9.6G*100)

/var use is (like all good things unix-ish) arbitrary but, apart from logs which often do grow to considerable size, is also the default location for 'in use' files like databases. For example,, both postgres and mysql will default to /var as the home for their potentially sizable database file. Rule of thumb? Declare /var to be LARGE in size. Most ofthe server crashes I have to deal with arise from exhaustion of the /var file system.
