dump 'ignore dir' option?
by Dave Cole 08 Dec '98

08 Dec '98

Is there any easy way of telling 'dump' to ignore one or more directories? It seems like every filer I archive has at least one HUGE directory full of unvital compressed files that causes the dump to span tapes. ---------------------------------------------------------------- Dave Cole (DC1110) | dacole(a)netcom.ca Systems Administrator |* dacole(a)rik.net * | office/~dacole/ Netcom Canada |* www.rik.net/~dacole/ * 905 King Street West, Toronto, M6K 3G9 | phone - 416.341.5801 Toronto, Ontario, Canada, Earth, Sol | fax - 416.341.5725

input request
by Patrick.Day.B＠bayer.com 03 Dec '98

I am having trouble with my tape changer and am curious as to if anyone else has this problem. I have a netfiler 740 (w/ Ontap 5.1.2) with a Quantum PowerStore L500 Library (DLT7000). It refuses to change tapes when I run the appropriate DUMP command. If anyone has experienced this and/or has a solution, any input would be appreciated. Thanx W.

SNMP and Quota trees
by Ketil Kirkerud Elgethun 26 Nov '98

26 Nov '98

We're using MRTG with our filers, and a smallish problem has cropped up : When querying for quotas, we really do not want to know the user quotas, just the tree quotas. This is easy if we feed MRTG with the index number of the tree, but one of our filers has, in addition to 2 quota trees, 65000 users. We do not want to sift through 65K entries just to find what interests us - is there any way to just query for quota _trees_ ? Does anyone have an elegant solution ? (yes, we _can_ use /etc/quotas, yes, it's possible to do an 'rsh filer quota qtree', but we'd rather use SNMP, if at all possible) -- ---Ketil Kirkerud Elgethun, SOL System

Re: snapshot and df does not match?

The percentages in snap list have always been a little confusing. I think they give you the amount of space the snapshot takes up relative to the total disk space used on the filer, and the total disk space available on the filer. Neither of which would relate to the space you've chosen to reserve for snapshots. I could be wrong, though; I don't have a man page handy and frankly, I've always pretty much ignored the values in snap list as they didn't really contain any useful information to me. All the 130% means is that you've exceeded your snapshot reserve. You have a couple of choices: 1. If you think this is typical and don't mind the space usage, increase your snapshot reserve. 2. If you think this is typical and DO mind the space usage, you will need to change your snapshot schedule to exclude, for example, the weekly snapshots. 3. If you think this is not typical, and you simply had a bunch of stuff deleted this week, you can either live with it for a day or two until it's deleted "naturally", or delete it manually yourself. There are some other things you could do too, but those are the main options. Bruce

RE: F630 grinds to a halt daily after update to 5.1.2?

Nope, 5.1.2P1 also has this problem. We're downgrading back to 5.0.1D4. They've been no help yet on the core files, so I think that's our best bet. -- mat.

First issue is: >Well, it turns out that there is some "feature" in NT that causes IIS to >hang if oplocks are on. To me, this is an issue with IIS. If you use IIS, you'll get this same problem when talking via CIFS to another NT box. The answer is to not use IIS (or NT entirely), or, as you point out, turn off oplocks. >The second issue is a hardcoded limit in the filer that does not allow for >more then slightly more then 65K of directories in one directory tree.

This limit is not documented >(there is a limit of approx. 300,000 file sin one directory and a maxfiles >limit that is dependent on number/capacity of disk drives that are >documented). This does bother me. I don't know when the limit appeared, as it doesn't seem to be a part of the WAFL design, and slipping it in through a "backdoor" without mentioning it is disturbing. As you mentioned, there is a limit on the number of files, or actually directory entries, in one directory, which was set as a matter of performance; however, there is a maxdirsize parameter you can set to increase it. Directories should naturally be treated the same way, so if you're correct that some other limit has been added (maybe it was always there and I just didn't know), it would be nice if someone from Netapp could address why this limit exists and if/when it will be lifted and/or made user-configurable. Mind you, if you tried to put 65K directories in your NT or UNIX server, you will run into a severe performance degredation. You really should look into setting them in deeper subdirectories. This appears to be another reason NOT to use IIS.... Bruce

F630 grinds to a halt daily after update to 5.1.2?
by Matt Stein 21 Nov '98

21 Nov '98

I know this isn't a support channel, but Netapp's not been useful at all, so what the heck: I have an F630 that's run well enough for five months. On Sunday we upgraded our filer to 5.1.2 from 5.0.1d4 at the suggestion of our Netapp SE. Since then, it's come grinding to a halt each day. NFS access starts getting really slow, and eventually completely unresponsive. Network activity is not high. sysstat shows that cpu, disk, and net are all getting lower and lower as clients start dropping their mounts. Things do not improve until eventually we reboot it. The telnet interface is fine and responsive all the way through. Netapp's support has asked for crash dumps, etc., but nothing's helped, and we're heading into a weekend. They also recommended *not* downgrading back to 5.0.1d4. Apparently 5.1.2 has bug fixes that we require(news to me). Has *anyone* seen this? Suggestions? Thoughts? Hitz voodoo solutions welcome. :) -- mat.

The v3 clients or the tcp clients could be *causing* the bug to occur in the netapp, which then consumes resources to kill all clients. So, changing the clients to a different mechanism may avoid the problem. Get it? Bruce
