Disk writes occuring when no network activity?
by Art Hebert 06 Mar '03

06 Mar '03

Would anybody know why I have disk writes occurring on my netapp when it is completely disconnected from the network. It is doing memory scrubs, but would this cause writes to the disk? Here is what sysstat looks like. As you can see there isn't any nfs, cifs or http activity. On my other filers that are hooked up to a network the Disk writes go to zero when there isn't any activity. smf760-01*> sysstat 1 CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 2% 0 0 0 0 0 0 762 0 0 59 1% 0 0 0 0 0 0 740 0 0 59 2% 0 0 0 0 0 0 752 0 0 59 1% 0 0 0 0 0 0 764 0 0 59 2% 0 0 0 0 0 0 788 0 0 59 1% 0 0 0 0 0 0 788 0 0 59 2% 0 0 0 0 0 0 784 0 0 59 1% 0 0 0 0 0 0 808 0 0 59 2% 0 0 0 0 0 0 804 0 0 59 3% 0 0 0 0 0 156 1108 0 0 59 2% 0 0 0 0 0 0 824 0 0 60 1% 0 0 0 0 0 0 868 0 0 60 2% 0 0 0 0 0 0 888 0 0 60 4% 0 0 0 0 0 0 880 0 0 60 2% 0 0 0 0 0 0 844 0 0 60 2% 0 0 0 0 0 0 892 0 0 60 2% 0 0 0 0 0 0 872 0 0 60 1% 0 0 0 0 0 0 880 0 0 60 2% 0 0 0 0 0 0 884 0 0 60 CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 1% 0 0 0 0 0 0 852 0 0 60 4% 0 0 0 0 0 164 1148 0 0 60 Thanks art

etc/log/snapmirror.log parsing

Has anyone written anything to parse the snapmirror logs to convert: dst Wed Mar 5 03:00:00 EST xxxxx:/vol/vol0/- yyyyy:/vol/vol1/xxxxx_vol0 Request (Scheduled) dst Wed Mar 5 03:00:04 EST xxxxx:/vol/vol0/- yyyyy:/vol/vol1/xxxxx_vol0 Start dst Wed Mar 5 03:51:58 EST xxxxx:/vol/vol0/- yyyyy:/vol/vol1/xxxxx_vol0 End (28215980 KB) into something a bit more useful, like: dst Wed Mar 5 03:51:58 EST bat07:/vol/vol0/- bat00bak:/vol/vol1/bat07_vol0 End (28215980 kB, 00:51:54, 530 MB/min)? which adds elapsed time and transfer rate? Or, something further that completely parses the log and reports: Source Size Elapsed Rate ------------------------------------------------------------------ xxxxx:/vol/vol0/- 28215980 kB 00:51:54 530 MB/min zzzzz:/vol/vol0/qtree 4345164 kB 00:16:13 262 MB/min [...] for all my snapmirror transfers for the night?

there is a snapmirror log parsing tool available on the tools section of NOW, if it doesn't do what you want it should be easily extendable (its in perl) from the NOW page blurb: SnapMirror Log Parser (parse_smlog) This Perl script is an example of how the SnapMirror log file can be parsed so that they can be more easily understood. This script runs under Perl5 and should run on most Unix based systems. steve. -----Original Message----- From: Todd C.

swapping heads
by Peter D. Gray 05 Mar '03

05 Mar '03

Does anybody know if it safe to simply swap heads between a F720 and a F740 filer? Since the OS and configuration is on the disks I assume this will work ok as long as the OS and/or configuration is not specific to either of these 2 models? Regards, pdg -- See mail headers for contact information.

Hi Peter, How's everything down Wollongong way? Thanswer to your question is yes, bearing in mind that the F720 won't [officially] support as much storage as an F740. They both run alphas so you don't even need to reload OnTap. You must halt the filer properly to make sure NVRAM is flushed. Then power down, swap the heads and boot it up. To go to in Intel based filer head (800 series) you would need to run through the regular OnTap upgrade procedure, including the "download" console instruction, with an Intel version of OnTap first. Then simply halt, power down and swap the heads just as you would normally. regards, Alan. -----Original Message----- From: Peter D.

Adding RAM
by David Schairer 05 Mar '03

05 Mar '03

We were told recently by someone who's now left Netapp that it's "routine" inside Netapp to to put more RAM (dynamic, not NVRAM) in 7x0 and 8x0-class boxes than the published maximum. I assume this is with higher-density memory. Has anyone outside netapp seen or heard this done? I'd like to know if it's been observed in the wild before I go try to get this rumor confirmed through our sales channels. --DRS

Snapvault and 6.4
by Frank Gilmurray 28 Feb '03

28 Feb '03

Anyone using snapvault w/ 6.4? We use snapvault to update a R100 and it was working fine until we upgraded to 6.4 yesterday. We upgraded to get the 255 snapshot limit. I've opened a case on this but was wondering if anyone else has any ideas on what could be going wrong. The client snapshot is fine but the server snapshot has yesterday's contents even though it says it was xfered this morning at 2:05. A directory I created yesterday shows up in the client snapshot but not in the server snapshot. None of the qtrees were updated last night. Thanks, Frank -- Frank Gilmurray Release Engineer Nokia, Inc. phone: (650) 625-2179 313 Fairchild Drive, Blgd. A cell: (650) 892-4029 Mountain View, CA 94043 email: Frank.Gilmurray(a)nokia.com
