RE: APC UPS Monitoring
by Gifford, Josh 23 May '03

23 May '03

We had a F720 in a site that had regular power problems. At times every weekend the power would be down for more than an hour which would drain the UPS and the filer would fall flat on it's face. As far as the filer was concerned, there were no problems. On occasion the virus scanner servers would not reconnect on their own though. -Josh -----Original Message----- From: Andrew Siegel [mailto:abs@blueskystudios.com] Sent: Friday, May 23, 2003 11:03 AM To: toasters(a)mathworks.com Subject: Re: APC UPS Monitoring As far as I know, NetApps can survive a power cut without a problem.

RE: Folder update time
by Alan McLachlan 23 May '03

23 May '03

Hi Chris, I had assumed that atime was stored in the directory entry itself (which would have a pointer to an inode that was a simple list of data blocks), which would have explained the behaviour reported by Jeff Burton in his post. TR2002 ("Filesystem Design for an NFS file server appliance") doesn't specify anything about directory entry contents. The testing you show below seems to nails it, but I will go and have a play when I get a moment just fo see it for myself. Now, even if the directory entry doesn't contain the attributes but is simply a name with a pointer to an inode that contains the file attributes, a change in the file attributes will still require the pointer in the directory entry to be changed to point to the new inode. (WAFL NEVER makes changes to existing inodes, it always writes new ones). Therefore the block containing that directory entry will still need to be rewritten (you seem to imply that it won't). If you are at least partly right it would mean that OnTAP is deliberately ignoring the change to directory entries in order to appear more consistent with traditional filesystem behaviour. This still doesn't help us solve Jeff's problem... -----Original Message----- From: Chris Thompson [mailto:cet1@cus.cam.ac.uk] Sent: Friday, 23 May 2003 12:48 AM To: amclachlan(a)asi.com.au Cc: toasters(a)mathworks.com Subject: Re: Folder update time Alan McLachlan writes: > > A write to a file will change the file size attribute in the directory > entry, which will of course change the mod time on the directory itself.

RE: Folder update time

Steve, Jeff, A write to a file will change the file size attribute in the directory entry, which will of course change the mod time on the directory itself. In fact, if you don't have "atime update" turned OFF, even opening a file will change the directory mod time since the access time attribute for the file needs to be updated in the directory entry. Remember, in WAFL all metadata lives in files. That includes directories. So ANY change to a directory entry will cause the modification time on the directory to be updated. This will in turn change the mod time on all relevant parent directories up to the root. On a traditional filesystem like NTFS or UFS this would be a performance disaster as it would generate lots of additional seeks, so they don't do it. However in WAFL an change to a file will cause all relevant metadata inodes up to the root inode to be rewritten [in new locations without seeks] anyway, without a performance cost. Hope this helps.

exportfs -u -a

(-root on a build host) I did an "exportfs -u -a" and to my horror all of the *existing* /usr/local mounts went stale. I do not remember this happening with Auspex's (in a previous life) and SunOS 4.1.2. Perhaps I need to go back to the blue NFS/NIS O'Reilly book....

There is currently no way to limit admin users. See burt 42514. However you can restrict rsh and telnet access with: options.rsh.access and options.telnet.access. For example: options.telnet.access "host=admin_host". This will only allow telnet from the computer admin_host.

I'm using the "useradmin" command to add users to my DOT 6.3.1 for CIFS authen since I don't have a DC. Unfortunately these users also become Filer Administrators and I have to be very careful not to let them onto the box. I'm looking at how to handle password administration for these users without letting them have a telnet session. Anybody use a "rsh" script to administers these user accounts? Any ideas how I can limit them? The only thing I've come up with is having our manned Help Desk administer a telnet session for them while the user is physically in the Help Desk area. Ideas? -Bob

Blast from the past. 5.3.1D9
by Jaye Mathisen 19 May '03

19 May '03

I have an old filer that we just didn't do much with. I powered it up, and it's crashing with a panic in wafl. Read a bug report that it is fixed in 5.3.1D9. The filer has 5.3.1 on it. I have the 5.3.1D9 tar files and stuff, but I believe the install uses the regular 5.3.1 disks. Are there any ways to get the 5.3.1D9 kernel on the floppy so I can boot it and let the wafl log finish getting replayed? There's nothing on there that's too critical, but I just want to double check.

RE: snapshot appearing in qtree
by Dell, Mary 19 May '03

19 May '03

Legato creates that directory on my volumes even when I'm not using snapshots. Anyway Legato backs up by creating a snapshot and then backing up the snapshot and then it (supposedly) deletes the snap, but if it fails mid-backup it might leave it out there. I assume other backup software works similarly. Not sure how to get rid of it. With at least one version of Ontap, trying to delete the contents of that folder panics the filer, so think twice before trying that! I found that out the hard way.

The sizes are right for a (3+1) x 72GB volume with 10% snapshot reserve, but the used/avail values make no sense to me. Is the "avail" for /vol/VLD_EXData/.snapshot really 18794972 rather than 8794972 (that could be a transcription error), which would be consistent with there being no snapshots. Is that what "snap list VLD_EXData" says? I don't know what to make of the zero avail figure for the active filing system ... Chris Thompson Email: cet1 [at] cam.ac.uk
