"Interrupted system call" to F230 news spool
by Brian Tao 17 Sep '97

17 Sep '97

One of my inn 1.4unoff4 news reader servers started throttling itself just today with "Interrupted system call writing article file" (happened twice in the past 24 hours). The spool is on an F230 running 4.0.3, 256MB of read cache and 4MB of write cache. The news server is an Ultra 170, 512MB of RAM, ~250 to 300 readers around peak times. The two are on a FDDI ring. The F230 hovers around 65% CPU usage, so I don't think that's the problem, but the Ultra is reporting 900 to 1200 packets … [View More]

Yeah, tar has bugs in differnet versions... and cp is just bad. I prefer "find . -print | cpio -pdumv /path/to/newdir" myself. However, long filenames with spaces in it can break this too. :) Gotta write a … [View More]

restoring from snapshot
by Christoph Doerbeck 26 Aug '97

26 Aug '97

Greetings, I've run into this scenario where a directory of "useful" stuff got deleted (about 7 gigs of "useful" stuff). At any rate, it all appears to be sitting in the hourly.1 snapshot as expected, but now I wonder... What is the best way to restore it? I`ve disabled the snapshots while my "tar cf - | tar xpf -" does it's thing, but is there a better way? I also wonder, since a "mv" blew away the directory in the first place (this is what I was told), can I "mv" the directory right back … [View More]

Very slow fcntl() calls from Solaris to F230
by Brian Tao 20 Aug '97

20 Aug '97

I noticed a very serious problem this morning on one of our news servers with a Netapp-based spool (Ultra 170, 1GB RAM, Solaris 2.5.1 + Aug 16 rec. patches). That server was recently upgraded from a 2.5 Ultra running INN 1.4unoff4 to the 2.5.1 Ultra running INN 1.5.1. Building or adding to the overviews files takes a *very* long time. I trussed the overchan as well as an expireover process, and I'm seeing a long delay (on the order of a minute or more) after one of the open() calls. I … [View More]

filers and ClearCase
by matthew zeier 18 Aug '97

18 Aug '97

My group's looking to rollout a ClearCase implementation soon. We're a heavy NetApp house and most obviously want to use our filers in any implementation we come up with. However, I'm getting mixed stories as to the roll my filers can play in with ClearCase. On one hand I have my Sun sales guy telling me all about Sun's drive solutions and how the filer "simply won't cut it". He's convinced that ClearCase won't work on an NFS box all together. On the other hand I have confusion - … [View More]

Backing up multiple Netapps
by Brian Tao 12 Aug '97

12 Aug '97

What do people do for enterprise-wide Netapp backups? It's nice to plug in a big tape drive into the dedicated SCSI port on each filer, but management becomes a hassle, and the hardware itself gets pretty expensive. If you centralize everything to a backup server and do dumps over the network, what do you use to manage the scheduling and auditing of the tapes? Is there a way to get Amanda to work with a bunch of Netapps? Anyone using NDMP-based tools? -- Brian Tao (BT300, taob(a)netcom.ca) … [View More]

Read errors on a spare disk?
by Brian Tao 11 Aug '97

11 Aug '97

Why am I seeing problems with a disk that isn't even active? Does the Netapp do periodic media checks on the spare drives? I had just added this drive in a couple hours earlier that day, and I've only seen this one occurrence so far.
