About expand size of a pool

Hi all,

Recently i have attached a 500G USB disk to Netware 6.5 server and then prepare to restore a large PO. but by mistake I have choosed to 'expand' the size to current pool (use NSSMU to a RAID 5/PERC) but not mount a new pool.

Then now I am not be able to retreive the partition/disk back since it is now a part of the pool. (Once you have expanded a pool, never try to shrink it again. If you delete any of the partitions belonging to a pool, NetWare will warn you that you will lose data, and then, if you proceed, it will delete ALL partitions belonging to the pool. )


I just wondering if there will be a way to get rid of the USB disk from the pool but not damaging the data/system on it? Or is there a solution for this?

there are 4 volumes in that pool. is there any suitble solution that I can get it back? Because the USB disk is on low performance and it is a risk that I am not sure how relaible it will be....

Your comment are highly appreciated, please help. thanks in advance.

I do not think there is, but you can ask people like PortLock if they
have an idea. If not, you need to back up (at least two, verified ones),
delete, recreate and restore.

Or if you have space, add disks, create a new volume and copy all data
there.

Re: About expand size of a pool

Hi Anders

Thanks for the reply. I also can see only way is to backup and re-create the pool. May I know if the below solution will good:

Mount another large size USB disk to current NetWare server and make it as a new Pool with 4 VOLs (same as the current pool), use the Novell NetWare Server Consolidation Utility to copy/sync the data from 4 current VOLs to new pool, make sure the data trustee rights were also copied as well as the restore is doable. Then delete the current Pool - VOL(include IMG/PROG/VOL1/VOL2) and recreate the Pool with old settings, final step will be copy/sync back the proper data from the new pool and test afterwards.

Seems like a plan?

thanks.

That should work, you can also use VCU to do the copy. I would
nevertheless make sure I have two verified backups on tape before doing
anything.

Re: About expand size of a pool

It should work, but pay attention to the fact that VCU does not handle
files bigger than 4GB because it was written to copy from TFS to NSS and
on TFS, there could be no such big files.

Re: About expand size of a pool

Hi all I'm not yet start to rebuild the VOL/Pool, now the server is having 3 Abends and I am going to give a reboot for the server on Friday.

Just wondering if the reboot will cause the disk problem? the SYS/Driver is on another separate POOL/VOL. I believe the driver and the partition will be loaded before mounting the Pools/VOLs? will it cause the disk inconsistent?

thanks

Re: About expand size of a pool

I don't really follow your question. Are you asking if rebooting the server will damage a disk or volume in some way? The short answer is "no". If you can perhaps clarify on what basis you are worried we may be able to answer more usefully.

Hi Andrew as I have mentioned above, we have added an usb disk to one of the POOL as it now become a partition. my question is that will it cause problem if the server is rebooted what if the USB disk performance may slower than other HDDs in PERC and cause the disk inconsistent during/after the reboot?

My answer is no since the sys and (disk/usb) drivers were loaded from another separated POOL/VOL which does not have the USB disk expanded.

kindly share your mind.

thanks
