Re: how to umount the cluster vg.

It depends on your configuration.


Halting the package will umount the VG, if part of the cluster.

Otherwise consider to halt the application, then umount the file system.

Hope this helps!

Re: how to umount the cluster vg.

hi

check your cluster configuration file

You can find entries to down

mount point --- umount =1
database in customer defined alias

if not down the database or application
halt package and then node.

Re: how to umount the cluster vg.

Well my first comment is that you have th esame VG active on more than one node, assuming this is indeed a Serviceguard cluster and you are using this VG in the cluster.

Have you tried :
umount /u105

Re: how to umount the cluster vg.

suppose you just want to umount /u105 alone,
1ï¼ umount /u105
2, if step 1 failed, telling"device busy", halt application on server 2, then umount /u105
3, if step 2 failed, fuser -ku /dev/vgdb1/u102, then umount /u105
of course you could halt package to umount the filesystem if it was configured in cluster.

Re: how to umount the cluster vg.

if you want to unmount /u105 ,first check whether this filesystem is using by any package, if this is apart of package conf the you need to do

cmhaltpkg pkgname

if not simply do

umount /u105

if saying device is busy

then fuser -ck /u105

then unmount it.
