F540 crashes while unlinking many files, Assertion failure?
by Ragnar Lonn 17 Apr '97

17 Apr '97

Hello, I have a Netapp F540 that has some 2-3 million files on its filesystem currently. I've been testing a news server setup on it and now I'd like to erase all these files, starting all over again with an empty filesystem. I did "rm -rf <dir>" (and no, I didn't erase the /etc dir on the Netapp) and it ran for a while, erasing lots of files, then the Netapp crashed and rebooted! I hoped it was a freak occurance so I did another rm when it got back up again but that made it crash once … [View More]

I do have a few thoughts and observations: 1) Writing to /var/spool/mail via the F330 (NFS) was a win for us in this case, especially once we increased NVRAM from 2MB -> 4MB. This particular F330 is used for other (general) access, … [View More]not just for mbox duty. Observations lately point to the need for more NVRAM at peak times, so we're going to 8MB shortly. The box gets really humped when it's stuck in constant physical disk writes. The old situation was a Fast-Wide SCSI disk attached directly to the UltraSPARC 1. That disk was doing way too much. 2) One of the reasons for migrating to the Toaster was to eliminate our mailhost from exporting /var/spool/mail. This enabled us to be able to do work on the mailhost/newshost without being too disruptive. The Toasters have to always be up anyway or all UNIX boxes hang. Our current thinking is that we might do well to go to a SPARCstorage array locally attached to the mailhost and *not* exporting /var/spool/mail at all, and forcing the use of POP3/IMAP. Those people using Elm will just have to use Pine. No big loss...in fact, a big gain. But making users change email software can be a pain, especially for the zealots who insist on performing every single action from within Emacs. Don't get me wrong, I love Emacs. But sometimes you gotta draw the line. 3) If you use POP3 you will be incredibly unhappy at times, especially if even a few users have large mailboxes. This is due to the way most stock poppers do mailbox locking. (write temp file called .user.pop and then write this file out again as user) Our current approach is to set a reasonable threshold on user mailbox sizes and email users informing them to check their mail settings and clean up. There are many variables here that relate mostly to POP settings in the client programs. 4) IMAP4 is pretty good. Use it if you can. It also solves a lot of the issues with being a mobile user. IMAP4 is better than POP3 in this respect. More like a true client-server mail package with all the benefits of having source code and not needing to open shrink-wrap. -- Dave Pascoe | mailto:dave@mathworks.com | Voice: 508.647.7362 KM3T | http://www.mathworks.com | FAX: 508.647.7002 PGP fingerprint: 53 AD 71 88 2F AA 45 AC D0 2E 68 91 71 77 39 AF [View Less]

Next Gen filer?
by alexei＠cimedia.com 10 Apr '97

10 Apr '97

Has anybody seen the next generation of filers? The plan that NAC has laid out for the future is pretty cool. Not sure what things are NDA, but I am eager to see some of the stuff that the HA dude is working on. May the three stooges prosper. Alexei /.

Mail Strategy
by John F. Kane 10 Apr '97

10 Apr '97

We are configuring three F330s into our enterprise architecture to serve /home data to our users. We currently use SparcServer 1000s for this purpose. We are interested in how other organizations are implementing UNIX mail in this situation. Is it best to put /var/spool/mail on the NetApp filers or keep it on the UNIX mail server? Thanks. -- John F. Kane Lead Staff, G052 The MITRE Corporation

Re: full duplex on FE
by Arnie Thompson 10 Apr '97

If FE means Fast Ethernet, the answer is yes for the PCI-based models (220, 330 & 540). You need software release 4.X to support full duplex.

NAC's CIFS
by Aamer Latif 09 Apr '97

09 Apr '97

I'd like to find out about using NAC's CIFS to support file sharing for a mixed UNIX+NT/PC environment. Specifically, how is file services performance when running both NFS and SMB on the same box. Also, how is level of integration of the a toaster running CIFS with an NT environment (e.g. support of domain security, WINS, File/directory Permissions, use of File/Server Manager tools). Any other experience information would be appreciated. Latif (a.latif(a)ieee.org)

Re: NetApp F220 worth it?

---} Yes, you can get a Sun and throw 20G worth of disks for about the same price ---} (or less) but you do not get the same performance, administration or ---} reliability. I do agree on two points above: 'administration' and 'reliability'. Upgrading the OS takes only a few minutes and so far the F200 has had 100% uptime. However, on the third issue 'performance', I'm experiencing slower (almost 50%) read performance from my F220 than from a Sun Sparc20 NFS server. This issue has been … [View More]

NetApp F220 worth it?
by Janne Frosen 02 Apr '97

02 Apr '97

Hello, I just joined this mailing list, mainly to hear comments about the NetApps in practice. Our lab is planning to (maybe) purchase a NetApp F220. The simple question is: Is it worth it? ie. where are the true savings that justify the high price? As a comparison, it's possible to get the same amount of NFS disk with 2-3 times less $$. Will the additional features make up for it.. What was the deciding factor for you to get it? (Sorry if this is a boring FAQ) //Janne -- Janne Fr|… [View More]
