RE: availtime command

`availtime full` is what you want. Unfortunately, on some DOT upgrades, the data gets reset.

RE: Raid reconstruct speed & simultaneous reconstructs
by Simon Ferrett 10 Sep '04

10 Sep '04

Interesting you mention the raid.reconstruct.perf_impact setting - I was a little confused about its real meaning... I thought (as you mentioned) that setting it to 'high' would increase the reconstruct speed. I then used the filerview web interface to go in and change the raid reconstruct speed to 'high' and it actually set this value to 'low' - the web tool seems to set it to the inverse of what you'd expect. (setting 'low' on the web interface sets this option to 'high' etc.) So I was a little curious as to if the setting had a different meaning than the one you (and I) initially thought it meant. (eg: perhaps it's meaning impact on reconstruct speed rather than system performance, so 'low' means the least affect on reconstruct speed and therefore the most impact on system performance) I left it at 'low' since I figured the web interface probably knew the meaning of the option a little more than I did...

However, you may be able to improve the speed marginally by using the raid.reconstruct.perf_impact option and setting to high. However, if your cpu's are already maxxed it probably won't make a lick of difference. --- This email message and any attachments are for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: [Fwd: More than one Admin machine for Netapps ???]

If you want to stay with UNIX, you can use the "smbcacls" program that is part of the Samba suite. That allows you to set Windows permissions from a UNIX client. Mark -----Original Message----- From: ken middleton [mailto:ken.middleton@durham.ac.uk] Sent: Friday, September 10, 2004 7:49 AM To: toasters(a)mathworks.com Subject: [Fwd: More than one Admin machine for Netapps ???] Anyone got any ideas about this one? I have a need to write a script to create qtrees on a Netapps Server. I have a UNIX Bourne shell script which does the job, however I need to set up windows permissions on them, specifically administrator = Full Access everyone = Read Access The default permissions are not appropriate when looked at from a Windows environment, so ideally I'd like to rewrite the script (it's not rocket science) to run from a windows environment and for it to carry on and do cacls operations on the qtree created. We've got Services for UNIX installed and have installed the Unix Tools but when I try to do an rsh to the Netapps, I get "permission denied" and "can't establish connection" messages. Anyone know how I can get around this? Can I somehow specify a second admin machine which is allowed to rsh? At the moment, the admin machine is a UNIX box.

New Simplified Monitoring Tool

Hello Toasters. Some may have noticed my search for a simplified monitoring tool awhile back. Alas, I never found such a tool. So I finally broke down and just wrote my own. So far I've only got about 2 hours worth of developement into it, but it's mostly what I want already. I thought I'd see if anyone else was interested in it or could propose suggestions for it. It's called "Toasterview" (I wanted to call it ToasterVision, but that seemed to silly) and you can see an example output page here: http://www.cuddletech.com/code/toasterview/europa.html Some notes about this sample page. Firstly, the Head image you see at top does, you'll notice, match the model of the filer so you can "see" what the head looks like reguarless of which model it is; right now F7x0, F8x0, F940 and F9x60 are handled.

My guess is that 6.5.1R1 was removed due to the many problems it had and replaced with the 6.5.2 offering. As I mentioned before, 6.5.2 is no bed of roses. So if you must go up, go for 6.5.2P6 to fix a couple of nasty problems. My experience with 6.5 says stick with 6.4 releases if you can. Unless you absolutely need the new features of 6.5.

RE: New Simplified Monitoring Tool
by Simon Ferrett 10 Sep '04

All the drives on the shelf disappeared from the system when it "wedged" so they were marked failed (or just missing). When I initially made the volumes, I organized raid groups such that there's only one drive from any given raid group on a shelf. So with 12 disks in a shelf and 7 shelves in the system (for example, on the R100) I have my raidgroup size set to 7 and make sure that when the volumes were created or expanded that the disks were added in groups of 7 by name, one from each shelf. I organized it that way exactly for this failure case - losing a whole shelf. When the drives disappeard there weren't enough spares to rebuild (until we powercycled the shelf) so most of the raid groups were running one disk short, but they didn't go offline since they only had one missing disk. Because the volumes didn't go offline, the disks couldn't be reassimilated into the system after the reboot because they were now out of date, so they all became spares. So basically the system has to rebuild one drive from each of the 12 raid groups on the system - two at a time. The netapp folks chalked it up to a bug and I updated them to 6.5.2. Luckily the systems are internally used so the downtime wasn't a huge deal. Not something I want to recur on a regular basis, and with data on the volumes it was a bit of a heart-stopper when it started happening. Lukcy for me I suppose there was no data lost.
