Re: Considering buying an F330
by Steve Gremban 31 Mar '97

I use the default 20% value for snapshot reserve. On an F330 our setup looks like this: 10 disks data (35.2 GB) 2 disks snapshots (8.8 GB) 1 disk parity 1 disk hot swap. Snapshot reserve usage stays about 20% to 50% except when the toaster gets full. As Jim Davis says in his message: >This has been a sticky problem with our F220. We currently use the >default schedule in the sysadmin guide, more or less, and that means >once you get close to running out of disk space you have a problem >-- deleting files just shuffles them from the filesystem to >.snapshot, so there's no net savings in disk space. And the >.snapshot space will cheerfully spill over the 20% default. In our case you can delete 8.8GB of data in a 2 week period (we keep 2 weekly snapshots) and see an 8.8GB increase in user free space. If you delete anything beyond 8.8GB you will not see any further increase in user free space. The 8.8GB snapshot reserve has been sufficient for us on toasters where I have restricted the type of data to interactive design databases. The toaster that I allowed simulations on could only run a few hourly and 1 nightly snapshot. regards, Steve Gremban gremban(a)ti.com ------------- Begin Forwarded Message ------------- On Mon, 31 Mar 1997, Steve Gremban wrote: > I restrict the data going to our toasters to that created > interactively by our designers using Cadence.

How does a Netapp toaster keep time?
by craig Rodrigues 31 Mar '97

31 Mar '97

Hi, I just got a Netapp box installed where I work, and the damn thing doesn't keep time properly. For some reason, the Netapp time keeps setting itself 2 hours behind the current system time. (We have a bunch of Solaris boxes mounting the Netapp). The sysadmin who looks after it in my office claims that Netapp tech support told him that the only why to correctly set the time is to type rdate on the Netapp box!!! This seems fishy to me because even after our sysadmin does this, the Netapp seems to drift back to 2 hours behind the current system time (of our Sun boxes). Any ideas? -- Craig Rodrigues craigr(a)gis.net

Sounds like a time zone problem. > The sysadmin who looks after it in my office claims that Netapp tech > support told him that the only why to correctly set the time > is to type rdate on the Netapp box!!! I haven't found any other way either. Not that rdate is a big deal, but I'd like to have it run regularly, *without* enabling rsh access to the NetApp. I'd like ntp even better, of course :-) Btw, our F330 is about 30 secs fast after 14 days of uptime.

Thanks for the kind words! However, lest anyone get too confused, our filers use RAID-4, not RAID-5. Still parity and the same degree of data protection, just on one disk instead of being interleaved amongst all disks as RAID-5 does. The advantage of RAID-5 is that you can use a traditional file system, designed for a single disk and not for RAID, and distribute the parity workload amongst the disks instead of it being focused on one disk. NetApp uses a file system designed for RAID to avoid the parity disk bottleneck. RAID-4 has the advantage of allowing you to expand the RAID group (even by just one disk), and of using disks of varying geometry in the same RAID group. RAID-5 requires all disks to have the same geometry and cannot itself be expanded, though you can expand the filesystem by concatenating an additional RAID group (not just one disk, and more space is lost to parity). -- Karl

Service is also an important factor, which NetApp is +very+ adept at. David, if you buy F330s, though, make sure they send you BLUE NettApp tee-shirts. We bought a pair of F330s last fall and are still waiting for ours. Maybe their sales department needs to take lessons from their support department... ho hum! -Caroline

Considering buying an F330
by David Drum 28 Mar '97

28 Mar '97

Hello anyone and everyone, I found the article announcing this list on comp.protocols.nfs via Deja News. Rather than lurk for a while, I need to jump right in and ask a leading question: If you the choice to make again, would you buy another Network Appliance, or would you get the biggest disk array you could find for the same money? Why? We're about to buy an F330, and I am in search of decision reassurance. I can't help but think I am splurging some. Regards, David K.

Re: "DU" lying on sunos5 machines
by Amy Chused 20 Mar '97

20 Mar '97

It's 'cuz Solaris du counts blocks, not K, and the netapp blocks are 16K, not 1/2 K. I think there's an option to du to tell it how big the bloody blocks are or to make it count K, not blocks. 'Course, if I remember correctly, that option is broken in the stock install, but there's a patch available from sun that fixes it, I think.
