Solaris 10 and ufs filesystem greather than 1tb

Posted in Solaris at 4:08 pm by alessiodini

Today i got a task about a resize. I have to grow a ufs filesystem more than 1 tb.
In my experience i learned that a ufs filesystem needs to be created with multi-terabyte support at beninning or this task will require a new filesystem creation !

I did not know how verify the multi-tera support , i looked on the web but i found an answer from colleague.
so let’s see 🙂
( ufs filesystem without support, i tried on my virtual machine )

vxlab:>fstyp -v /dev/rdsk/c2t0d0s2 | head -2
ufs
magic 11954 format dynamic time Wed Feb 22 15:41:04 2012

( ufs filesystem with support , i tried on my virtual machine )

vxlab:>fstyp -v /dev/rdsk/c2t0d0s2 | head -2
ufs
magic decade format dynamic time Wed Feb 22 17:05:38 2012

So , when decade exists we have a multi-tera support! 😉

    You need to check if the filesystem was created using the newfs -T command [check man page], If it was not created using -T option, you cant extend it beyond 1TB. Use mkfs -m to check.
