clustering filers
by Jeff Kennedy 04 Mar '02

04 Mar '02

A quick question regarding NetApp filer clutering. How well does it work? Would you spend the money again? Problems you've encountered that make it of questionable value. We are putting more and more applications on the filer that are considered 24X7 when the filer itself is not. Granted, they are extremely reliable but the fact is that they have several single points of failure. I am looking at clustering filers as a way of fixing that. The other possibility is Veritas ServPoint HA on SAN. Thanks. -- ===================== Jeff Kennedy Unix Administrator AMCC jlkennedy(a)amcc.com

Random Trouble with AMANDA
by Jamin A. Brown 01 Mar '02

01 Mar '02

Hello, Looking for any ideas (or possibly even a fix!) from you fine people about a problem we are having. Background: We recently started backing up our NetAPP 720 Filer using a combination of AMANDA and the scripts located at: http://www.xs4all.nl/~johnpc/amanda-netapp.html The server we are using is a dual PIII 800 running FreeBSD. Due to the size of our tape drive (35GB), we have to perform subtree backups. Due to how the NetApp was setup, we're doing 40 subtree backups from the same volume each night... The Problem: Every night, no matter what, some of the backups fail for various reasons (see below). The thing is, these failures are random. A subtree that had problems one night will not have problems the next... I have indexing turned off, and have replced restore with a wrapper as recommended in the article here: http://groups.google.com/groups?hl=en&frame=right&th=25ab1f922c37dcf3&seekm… FAILURE AND STRANGE DUMP SUMMARY: magneto /dev/moya/home/customers/9 lev 0 FAILED [disk /dev/moya/home/customers/9 offline on magneto?] magneto /dev/moya/home/customers/8 lev 0 FAILED [disk /dev/moya/home/customers/8 offline on magneto?] magneto /dev/moya/home/customers/n lev 0 FAILED [disk /dev/moya/home/customers/n offline on magneto?] magneto /dev/moya/alias lev 0 FAILED [disk /dev/moya/alias offline on magneto?] magneto /dev/moya/home/customers/7 lev 1 FAILED [no estimate] The Solution? If anyone has any pointers on things to try, I would greatly appreciate it. We'd like to be able to fix this and stay able to use subtree dumps, and not have to replace our tape drive (which would require the replacing of the library the drive is in due to some bad things...). Thanks in advance. Jamin Brown GWI Operations

RE: Reducing volume size

You could use a utility for mirroring files called RoboCopy, I believe this in the Resource Kit for Windows 2000 or NT. Here is the help text output: ---------------------------------------------------------------------- ROBOCOPY v 1.96 : Robust File Copy for Windows NT ---------------------------------------------------------------------- Started : Fri Mar 01 11:22:58 2002 Usage : ROBOCOPY source destination [file [file]...] [options] source : Source Directory (drive:\path or \\server\share\path). destination : Destination Dir (drive:\path or \\server\share\path). file : File(s) to copy (names/wildcards: default is "*.*").

Re: Different size disk in the same raid group
by Jeff Kennedy 28 Feb '02

The reason is someone added 9gb drives to an 18gb drive volume ( or vice versa, hard to tell which was first ). They're not different effective disk sizes, they are different *actual* disk sizes. Effective size diff would be RAID Disk HA.ID HA SHELF BAY CHAN Used (MB/blks) Phys (MB/blks) --------- ----- ------------ ---- -------------- -------------- data 8.18 8 2 2 FC:A 8600/17612800 17366/35566480 Which is not the case.
