Wassup Skunks, Got this strange reading from my 'df -h' output on Sol 10: Filesystem size used avail capacity Mounted on ... /dev/md/dsk/d30 9.6G 8192E 0K 92365229983016% /var ...
From 'du -sh *' of / it shows that the size of '/var' is 1.7G. Any ideas what the output above means?
KR, Loki "Excellent people exceed expectations".
I'm a bit rusted on this but usually VAR partition holds temp files which should clear on reboot.. or some application is building up temp files nut not clearing. maybe other gurus on list can correct. :-)

9.6 G is the size of the partition ... 16% is in use

this gives you the 'in use' output for /var. .... (the actual size on disk)
Actually the /temp file holds temporary files that are lost upon a reboot but the var is usually for logging (i think) On Tue, Jun 30, 2009 at 5:16 PM, Ashok Hariharan <ashok@parliaments.info>wrote:

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) "Excellent people exceed expectations". ________________________________ From: Mick Wilson <Mick.Wilson@unep.org> To: Skunkworks forum <skunkworks@lists.my.co.ke> Cc: Skunkworks forum <skunkworks@lists.my.co.ke> Sent: Wednesday, July 1, 2009 12:10:08 AM Subject: Re: [Skunkworks] Size of /var? /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.

Does Sol 10 have a journaling utility? its a UFS file system I presume. On 7/1/09, Nicholas Loki <lokimwenga@yahoo.com> wrote:

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