Disk space crunch.

[joe_91]

Team:

We are upgrading Omniback on 10.20. we have only 150 meg on /opt and our upgrade requires more space. Is it possible to install this on say /opt/master (it is a seperate file system which has the required space) and then link it to /opt/omni? we install the omniback as a fileset (swpackaged). The whole idea is to get rid of the space issue in /opt and we cannot free any space there.

Best Regards
Joe.

Hi,

It sounds like it should work. As long as the permissions are all correct, I don't see how OmniBack and swinstall could complain. Do you have enough room to make a new LV & filesystem for /opt/omni? It probably will work just as well, and it might be less confusing.

You won't have any problems. If I remember the steps right, you swremove the OmniBack that you have which preserves the DB and then install the new one. Remember to print out you license keys. I split out my DB on a seperate filesystem /var/opt/omni/db40.

Hi:

Thanks. Can someone help with the steps please.

Best Regards

Hi again,

Which steps? For the OmniBack 4.0 upgrade? Or for making the LV and filesystem? By the way, Thomas is right. We made separate /var/opt/omni/db40 filesystems for the systems we upgraded to OB 4.0.

Hi John:

Thanks. I mean the steps to install in /opt/master(where we have space) and then link to /opt/omni so that it works fine. we already made the package for the upgrade. We just have to swinstall it.

Thanks
Joe.

Just to give you another way of looking at your problem - there is no rule that says that /opt must be in vg00. In fact, the only guys that MUST be on the boot drive are /stand, /, and primary swap. One alternative would be to make a new filesystem on another VG and copy everything in /opt over to /tempopt and then mount the new /opt.

Thanks clay:

Good option. But we cannot create a seperate VG. The reason is this package would be installed in multiple sites and in all the sites we have crunch on /opt but /opt/master is OK. Given this situation what would be the best option.

Thanks
Joe.

Joe,

I agree with Clay, but if you really want to use your /opt/master mount, here is one way to try it (assuming you have a good backup copy of everything before you start):

1. Stop OmniBack.

/sbin/init.d/omni stop

2. Move all your existing /opt/omni files over to /opt/master/omni (emptying out the old /opt/omni so you can reclaim the space)

mv /opt/omni /opt/master

3. Create a symlink for /opt/omni to point to /opt/master/omni

ln -s /opt/master/omni /opt/omni

4. Restart OmniBack and try your upgrade.

/sbin/init.d/omni start


These steps will stop OmniBack, move everything in /opt/omni to /opt/master/omni, and restart OmniBack. I think you'll need to do that rather than trying to swinstall it directly into /opt/master/omni.

Good luck!
