Increasing the filesystem with Ignite. Do I need fbackup?

[dictum9]

I need to increase some volumes that cannot be grown dynamically, (contiguous) like /opt, /stand and so on.

I have an Ignite tape I just made.

Do I also need a fbackup tape made?

Any other precautions?

It is a A class running (non-supported) 11.0.

Hi:

Your Ignite 'make_tape_recovery' tape has everything you need. Create it for vg00 only. Non-vg00 filesystems will be (vg)imported when you restore from it by performing an Advanced mode Media-only installation.

When Ignite executes, you will use the "Filesystem" tab to resize the filesytsems according to your taste. Be sure to specify only the disk you want for vg00.

Hi (again):

By the way, unrelated to this post, you never closed your previous discussion:

As long as you pick the same disk and do not re-install over the top of your data disk all will recover nicely. This exactly what the tool is for.

If using just a single disk then HPUX will be restored with current settings along with the filesystem and mountpoint ( no data ) for your data. Then simply restore your data where it belongs from your fbackup.

FYI, If only /tmp or /opt or /usr or /var needs to be expanded then you can do that in single user mode. ( assuming you have free extents in vg00 )

It is rare that /stand requires enlarging unless you are keeping many copies/versions of the kernel.

How long might it take to do a recover?

[Tim Nelson]

If you are talking about running the OS recovery from the tape you made it depends on the size and speed of the server. I would say 45m-1hr30m

If you are talking about the data backup made with your fbackup. That depends on how much data and the performance of your disks. At least as much time to back it up in the first place maybe more if you end up with a write bottleneck.
