AusCERT Security Bulletin Summary
Product: Solaris Volume Manager (SVM)
Publisher: Sun Microsystems
Operating System: Solaris
Impact: Denial of Service
- --------------------------BEGIN INCLUDED TEXT--------------------
Solution Type: Sun Alert
Solution 237505 : Adding a host to a SVM Metaset deletes the Set
Bug ID: 6579910
Solaris Volume Manager, Solaris 10 Operating System
Date of Workaround Release: 09-May-2008
SA Document Body
Adding a host to a SVM Metaset deletes the Set Name link
Adding a node to an existing Solaris Volume Manager (SVM) metaset may
cause commands that use the metaset to fail and may also cause a
Solaris Cluster failover to fail.
2. Contributing Factors
This issue can occur in the following releases:
* Solaris 10 with patch 127986-01 or later
* Solaris 10 with patch 127128-11 or later
1. Solaris 8 and 9 are not affected by this issue
2. This issue can occur for SVM without Sun Cluster installed.
3. This issue will affect both Solaris Cluster 3.2 and 3.1
withSolaris 10 and patch 127986-01 (SPARC) or 127128-11 (x86)
After adding a node to an existing metaset, commands that use the
metaset may fail as in the following :
# newfs /dev/md/nfs-set/rdsk/d0
newfs: /dev/md/nfs-set/rdsk/d0: No such file or directory
A failover or switchover in Sun Cluster may fail with the error:
cl_runtime: [ID 741078 kern.warning] WARNING: Switchover error
(/global/<mountpoint>): failed to mount FS (2)
On the node that was added to the metaset, run the command:
("metaclusterbinddevs" is a Sun Cluster command that will create the
missing links in /dev/md).
Example: If there is an existing metaset "foo", and pnode1 is
currently the primary:
A user adds pnode2 to the metaset with the command:
pnode1# metaset -s foo -a -h pnode2
Then as root on pnode2 run the command:
If not running Sun Cluster, the link will need to be created manually.
Determine set number from pnode1:
pnode1# ls -l /dev/md/foo
lrwxrwxrwx 1 root root 8 May 1 17:36 foo -> shared/3
Create the link on pnode2:
pnode2# ln -s /dev/md/shared/3 /dev/md/foo
A final resolution is pending completion.
