RE: RCS issues with ONTAP 5.4.3R2

Sniff is produced by a company called MKS. I dont know if they have a web site, but we get our licenses etc through wind river. Bye Simon -----Original Message----- From: Todd C.

If I had read the description of bug 21019, I wouldn't have needed to post my wild-ass guesses. I filed that bug. ;) That bug was a re-introduction of bug 7111, which a former admin of our company filed years ago; it apparently got reintroduced into the code base for ONTAP when another much *larger* customer of NetApp's demanded it work *their* way, not according to the UNIX-style semantics. The option cifs.perm_check_ro_del_ok then got created to fix 21019 (and 7111, *again*) to make it work as it should. So, this product...Sniff, who makes it? We haven't found an RCS tool for pc's that doesn't corrupt our RCS files, but I haven't heard of this one yet. Until next time...

It surely would.

- The only "plex" I can think of in VxFS is "complex"... :) - I believe that this shrinking has very strict demands - you must defrag first, have enough space of course, and it probably takes hours... - A filer tries to distribute data over the spindles, so it makes it hard I believe. Anyway, you have the option to create large volumes, and seperate them logically to easily growing/shrinking qtrees, which are like filesystems. - About your specific problem - easy fix - just create new volume with two disks. mount it. Use a tool like rsync to copy all the /etc to the new volume. Run "rsh toaster0 vol offline myoldroot" - this is for taking it offline during the reboot (NOT NEEDED IN 6.0!!!). Run "rsh toaster0 vol options mynewvolume root" and then after one last rsync reboot. There you have it. It was done on a production system by myself - no problem. After some time you can of course issue: "rsh toaster0 vol destroy myoldroot" to erase volume. eT. --- Aaron Sherman <ajs(a)ajs.com> wrote: > On Mon, Aug 21, 2000 at 12:38:40PM -0700, Eyal Traitel wrote: > > It would be lovely if there was such a RAID-filesystem... > > If anyone have heard of such - share with us... > > As noted by another, Veritas is capable of this.

Anyone actually done this? I tried once on Veritas V2.5.xx, something like that, and, although the docs indicate shrinkage is possible the s/w didn't allow the operation. I had to offload the data, remove the volume & start over. Now, this was Veritas on a Solaris machine.

As noted by another, Veritas is capable of this. I've included an excerpt from the docs, below: [begin vxassist man-page] NAME vxassist - create, mirror, backup, grow, shrink, and move volumes [...] shrinkto and shrinkby Decrease the length of the named volume to the length specified by newlength (shrinkto), or by the length specified by lengthchange (shrinkby).

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

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.
