Solaris 2.6 changed available space on external drive

Solaris 2.6 changed available space on external drive

I just installed Solaris 2.6 on a SPARCstation 20.  I had some external
drives that I did not re-format or change.

Before the install, I was running 2.4.  Here is the stats from "df -k"
for one of my externals in 2.4:

Filesystem                 kbytes        used           avail
capacity    Mounted on
/dev/dsk/c0t2d0s6    1298506    1129508    104073    92%          /disk5

Now under 2.6 it reads:

Filesystem                 kbytes        used           avail
capacity    Mounted on
/dev/dsk/c0t2d0s6    1298506    1129508    166401    88%          /disk5

It has the same "kbytes" and same "used", but I have more "avail"able
space.

I'm not complaining, but . . .
Anyone know why?

Thanks,
Marty

It looks as though you had newfs'd (or tunefs'd) this filing system with
a smaller-than-default (5%?) root reserve. This is an area in which there
are known to be bugs in Solaris 2.6 out-of-the-box. Make sure you have
applied an up-to-date version of patch 105572 (/kernel/fs/ufs fixes).
Of course, like all the best patches, it's not on the Recomended list!
