You can do it with a combination of VxVM and VxFS - and it's relatively simple too. The day the WAFL gets that feature, well, the VRTS solution won't look so simple anymore, of that I'm confident. (IF WAFL gets it, of course..) -- -Mark ... an Englishman in London ...

Removing disks from a volume
by Aaron Sherman 21 Aug '00

21 Aug '00

We've accidentally added our spare disk to a volume. Our OEM says that this is irrevokable, and that we'll have to copy the volume to another disk tray, rebuild the volume and copy back in order to fix this. Is that true? Is there no way to shrink a filesystem and remove a disk once it's been added? It seem contrary to the ultra-flexible spirit of the Filers.... -- Aaron Sherman Systems Architect HighWired.com -- The global high school community http://www.highwired.com 300 North Beacon Street Watertown, MA 02472 (617) 926-1850 x238 (617) 926-1861 fax asherman(a)highwired-inc.com / ICQ#43677395 / Y!ajstrader "We had some good machines, but they don't work no more." -"Faded Flowers" / Shriekback

RE: RCS issues with ONTAP 5.4.3R2

In answer to Todd's question: We use RCS as a backend to Sniff, on both UNIX & PC. The issue was correctl spotted by Mark. We have found that the bug mentioned did in fact cause our problems (prehaps Mark implemented the fix?) So if you are using source control, watch out! Cheers Mark et al for your advice and help with tis, it was kind of a major problem for us. Simon -----Original Message----- From: Todd C.

Sorry, more clarification suggested.... We have a call open with the support team, who are at a bit of a loss too. I was hoping that there would be a user out there who has seen this too... We went up from 5.2.3 to 5.3.4R2. The user working on UNIX boxes are able to be checkout file with RCS exclusive locks. Users on PC's get "permission denied" The user "eegbuild" owns most of the files in the share where the problem is being experinced , however this has never caused an issue. We have fond that once the users check out files on unix (which changes ownership to them) then they can check out when working on the PC. Likewise, user can check out files owned by users other than eegbuild. The problem appears to be on the CIFS side of things. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson] Sent: 17 August 2000 16:38 To: toasters(a)mathworks.com Subject: RCS issues with ONTAP 5.4.3R2 Hi! We have upgraded (downgraded??) to 5.4.3R2. Everything seems to work apart from RCS access. User can open and lock files on UNIX boxes OK. However on PC, users cannot open and lock files that have been created by another user. This operation work fine up until this upgrade (Previously we were on 5.2.3) ANY ONE? cheers Simon Simon Clawson Renoir Group Systems Administrator Mentor Graphics Uk Rivergate London Road Newbury Berkshire RG14 2QB <<Clawson, Simon.vcf>>

If you won't upgrade to 3.4, you can still "trick" NetBackup by entering the IP address for the alternate host in NetBackup machine's /etc/hosts. This is simple, and working too.

Standard NetBackup operations are all you need. Don't you have NetBackup manuals? The NetBackup NDMP System Administrator's Guide covers the questions you asked earlier - wildcards and exclude lists. __________________________________________________________________________ Steve Kappel steve.kappel(a)veritas.com VERITAS Software steve.kappel(a)iname.com (Personal)

Re: restore going nuts!
by Eyal Traitel 18 Aug '00

You can try to use "rsync" - basically circumventing the problem. It will also be easier for you to find out on these bad files errors since rsync mentions things like "stat()" errors - easier to diag.
