OSSV "incremental forever
by Halton, Robert 08 Nov '07

08 Nov '07

Can someone explain incremental forever to me in simple terms? If I do an initial baseline, and it's 100MB. Assuming a policy where we have 2 week retention on the snapvaults So 2 weeklies, 4 nightly and 8 hourly. Will it always be 100MB + the incrementals? thanks This message is intended only for the person(s) to which it is addressed and may contain privileged, confidential and/or insider information.

Are there any firewalls (or similar) between your two filers? I've see cases where firewalls will drop long-running sessions. So maybe it's not 83GB, but it's really N minutes? Davin.

Poor performance
by David McWilliams 07 Nov '07

07 Nov '07

We have a FAS270, single shelf running 7.2.2. Since Monday morning it has really started to slow down. There has been no appreciable change in the environment, ie no large data additions, no increase in users, no hardware failures, etc. The messages file is only complaining about being unable to bind to a particular WINS server and being unable to get to our ntp server, both issues we are aware of and working through - neither should cause this though. The 'ps' command provides a huge amount of data, mostly meaningless. The 'statit' command is almost undocumented. Does anyone have any recommendations about where to start looking? -- Sláinte, David Get a safer, faster, better web browser @ http://www.mozilla.org/products/firefox/

How many 750G disks can can fit into an aggregate?
by Stephen C. Losen 07 Nov '07

07 Nov '07

We're going to buy some shelves of 750G ATA drives. An aggregate is limited to 16T "raw" (which I presume includes parity disks). Not having any 750G drives yet, we don't know what they size down to. Can anyone tell us how many 750G disks (including parity) that you can stuff into an aggregate? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

In order to bring it online, you must either destroy and re-create the volume, or complete an initial snapmirror transfer or vol copy.

Make sure you're pointing your browser at http://filer_name_or_ip/na_admin Http.rootdir only applies when serving general-purpose http (statis content). Nothing to do with admin.

accessing lun as a raw device using dm-multipathing from a rhel host
by Alexander Schalek 06 Nov '07

06 Nov '07

Hi! I have some troubles with a oracle rac installation on netapp fcp luns. We use rhel4 u5 with dm-multipathing with a 2.6 kernel Currently we have 4 partitioned and multipathed luns maped to the hosts(mpath0-3) but the rac installation exits with an error. I found the following lines in the fcp host utilities setup guide: Accessing LUNs using dm-multipath Accessing LUNs as a raw devices Overview Instead of creating a file system, you can access a LUN as a raw device. Be sure to use the /dev/mapper/ device created by dm-multipath to access the raw device. For the Linux 2.6 kernel used by RHEL 4, do not use the raw interface. Instead open the device using the open call with the O_DIRECT flag. ***** So I have to access the devices using the open call with the O_DIRECT flag!? Can anyone of you guys explain this sentence to me? How do I do that? Many thanks and best regards, Alexander
