Solaris 10 Update/Release Date Chart

Jan 12, 2009
Solaris, UNIX

About once a week I have this issue – figuring out when a particular feature of Solaris 10 was made available. And if someone says “update 4″, is that 08/07 or 11/06? Here’s a chart that may help:

Release Date Update # Release Notes
01/06 Update 1 Solaris 10 01/06 Release Notes
06/06 Update 2 Solaris 10 06/06 Release Notes
11/06 Update 3 Solaris 10 11/06 Release Notes
08/07 Update 4 Solaris 10 08/07 Release Notes
05/08 Update 5 Solaris 10 05/08 Release Notes
10/08 Update 6 Solaris 10 10/08 Release Notes


Or, here’s a PDF from Sun that shows all the releases and the notes for each:

Solaris 10 mount point permissions are important

May 13, 2008
Solaris

rm: cannot determine if this is an ancestor of the current working directory

This is caused by an underlying mount point permission that is too strict (700). You can change the permissions on the mount point without unmounting the volume by using lofs creatively:

#create temp directory

server1> mkdir -m 755 /fix-mnt 

# mount the directory which contains the mount point, not the mount point itself, but its parent directory.

server1> mount -F lofs -o nosub /users/zones/server1-z3/root/users/  /fix-mnt
server1> ls -ld /fix-mnt/mountpoint        #confirms the permssions are not 775
server1> chmod 775 /fix-mnt/mountpoint
server1> umount /fix-mnt
server1> rmdir /fix-mnt

Speed up metasync

Apr 21, 2008
Solaris

It’s amazing how slowly a resync happens with Solaris Volumen Manager (SVM). You can dramatically reduce your time to sync up your mirrors with SVM by adding a setting to /etc/system and rebooting.

set md_mirror:md_resync_bufsz = 1024

I’ve tried 2048 (the max) as well, but not as big a gain in speed, so I stick with 1024.

Harmless on “modern” Sun machines. Just don’t try this on your SPARC 20 or it may lock up on you. As long as you have >1GB of RAM you’ll probably be ok.
