SAN backups of filers
by Garrett Burke 01 Sep '00

01 Sep '00

Hi All, Anyone out there using a SAN to backup their filers to a centralised library? (See NAS Neets SANs http://www.vixel.com/whitepapers/ and http://www.netapp.com/tech_library/3080.html) We are investigating this option and would be interested in hearing about any experiences people have had? Thanks, GB -- Garrett Burke, Operations Manager Eircom Multimedia Infrastructure Internet House 26-34 Temple Bar.

accessing mixed-case files on Netapp
by Eric Seidman 31 Aug '00

31 Aug '00

I was directed to this mailing list as a good source of knowledge about accessing files on Netapp. I hope this question is appropriate; if not, I apologize. I am working in an environment in which a Netapp filer containing files with mixed-case names is being accessed using both CIFS and NFS. It is important that I be able to access the files using NFS in a case-insensitive manner. Unfortunately, converting all of the filenames to a consistent case is not an option. The NFS access is being done from a RedHat Linux server running Apache. I have considered writing an Apache module to parse the directory structure to determine the actual case of the filename, although this option seems too inefficient. Any suggestions would be greatly appreciated. Thank you very much for your time, eric seidman eseidman(a)cs.stanford.edu

Workaround for Burt 23129?
by TTSG 30 Aug '00

30 Aug '00

Hi, Has anyone heard/seen a work around for Burt 23149 : If an NFS over UDP request is received on a filer's interface and therequest is for the interface's secondary/aliased IP address, the filerwill always respond using the interface's primary (real) address.This can cause NFS mounts to hang if the aliased address is on adifferent subnet than the primary address.

Recommendations/Opinions on the NetApp F720 filer
by lgkloft＠usgs.gov 30 Aug '00

30 Aug '00

I have a fairly small office (approximately 45 people) and perform GIS (geographic information system - ESRI ArcInfo) work, environmental modeling/database, reports writing, and other administrative tasks (email and web surfing). I am looking at the F720 fileserver (7-36GB drives, NFS, CIFS) to consolidate the $HOME and $PROJECT areas on my computer systems, and perhaps eventually the databases. The majority of my office is UNIX, but the number of PCs (as clients) is steadily growing. I am able to backup the UNIX boxes (servers) quite easily (~25GB), but the PCs are going to complicate matters. I realize this isn't much information to go on, but for those of you who are currently using the F720 - overall, are you happy with the performance and is your operation similar to mine (or larger)? How does your F720 respond to network traffic over the onboard 100-Base-T connection - is it a bottleneck? Do you utilize the QFE option (four 100-Base-T board) and did you designate certain protocols (NFS/CIFS) or servers to a particular IP address (pipes)? Do you now use the 1000Base-T connection - and how does/did this compare to the QFE option described above (if it was replaced)? Do you have any experiences/recommendations to provide on interfacing the filer into the LAN? How do your PC users (with local 10,000RPM disk drives) find the access speeds to their files on the file server - are they content or do they receive better performance having their data local on their drive? I have pulled numerous documents from NetApps WWW server (haven't read them all yet). Any closing comments/experiences (things to look out for, or plan for, etc.) positive or negative on the F720 would be greatly appreciated? Thanks, Loren

Snapshots and the block allocation map [was: Alot minus alot equals some?]
by Chris Thompson 30 Aug '00

30 Aug '00

I wrote: > [...] the block allocation map (4 bytes per 4K block on the data discs) [...] > The former, in particular, does not have its blocks deallocated just because > they have reverted to being all-zero. It occurs to me that one thing that causes the allocation map to expand to its maximum size rapidly in a new volume is taking a snapshot. And *that* reminds me about one of the promises about ONTAP 6.0 in Field Alert #66: | * Enhanced Snapshot functionality to provide near instantaneous | snapshot creation/deletion and increased snapshot count from 20 | to 31 per volume The main reason taking a snapshot is not "nearly instantantaneous" at the moment is that the block allocation map gets completely rewritten. (And as a result, there's a space overhead of the size of the map times the number of snapshots less one.) It would be interesting to know how NetApp have reworked the internal structures to get round this. But maybe it's Confidential Information and we'll have our lips stapled together if we start speculating... :-) The maximum of 31 snapshots suggests that the basic style of a 32-bit word of allocation information per block still persists.

Re: Splitting large volumes
by Eyal Traitel 30 Aug '00

30 Aug '00

The easiest solution, that also demands minimal downtime is using ndmpcopy/rsync altogether... This will work only if you have free volumes on the new machine... 1. Copy a baseline copy of the seperate parts of your current volume to the target volumes, using ndmpcopy/rsync/tar/whatever (ndmpcopy will be the fastest probably). This can be done while users are working, a few hours/days before the migration downtime is planned. 2. In something like a few hours before the downtime, use the utility "rsync" and/or ndmpcopy to copy incrementally the changes since the baseline. 3. DOWNTIME - while in downtime, just do a final syncing, again using ndmpcopy incremental/rsync, and change the relevant settings: NIS maps, filer's /etc/exports, /etc/quotas...

Completely shut off snapshots & reserved disk space

Many people replied to my question about turning off snapshots. I guess it comes down to it, which method not only turns off the snapshot, but also turns off the systems reserving of disk space.

This is very interesting to me, as I am about to do almost exactly the same thing. We have (don't laugh, please) a single 700GB volume which I want to split in to smaller volumes. To do this we have purchased a new 760 with 8 shelves ( we need more capacity anyway). What I plan to do is use rdist or rsync to copy the data from the old volume to the new volumes. Once the initial (level 0 ) copy is done I will keep up with daily incrementals until such a time as we can arrange a short down time to do a final copy and then re-rack the shelves to split them across the two heads. Hey presto. I've decided not to use ndmpcopy as a colleague of mine had an absolute nightmare with it when he moved from SCSI to FC-AL.
