The fileserver is running Fedora Core 5 and OpenAFS 1.4.2 (new machine). Similar behavior using 1.4.0 and 1.4.1 windows clients and 1.4.1 fileserver. I'd suggest trying the 1.5.10 client. I have a couple people with 1.5.10 clients installed, and they experience the same behavior. I am now borrowing a WinXP box and it's sitting on my desk. I experience the same behavior. When opening images in Photoshop from AFS, they load rather slowly, compared to opening a file on the local drive. This isn't unexpected. However, if I open the file from AFS into another image viewer, it shows up pretty much instantly. (This behavior is independent of which I do first, and is repeatable, so I don't think it depends on whether the file is in the cache.) How big are the files? Are they larger than the AFS cache on the client? Files are about 2-4 MB. Cache is 98MB (256MB on some computers). Now the weird part If I copy some image files from AFS to the desktop, and then drag them into Photoshop, they still load slowly AND the CPU usage on the afsd daemon goes up to 50%. Just seemed kind of weird that the afsd daemon gets triggered after the files have been placed on the desktop. The high CPU usage is likely from encryption. fs setcrypt off and re-run the tests. fs setcrypt off seems to have no effect. What does have an effect is whether or not AFS is running... even if the files are on the local hard drive. I'm still doing some testing to figure out what exactly triggers the behavior. If I restart the AFS service, and don't get tokens, things are quiet. If I get tokens, I think it's still ok. When I start accessing files in AFS, things slow down. And then even if I access files on the local drive, it stays slow. I think it may be related to when I open one of those wonderful directories with >2000 subdirectories. I ran out of time today, but will continue to investigate to see if I can nail down exactly what's triggering the behavior. What kind of hardware are you using on the client? I've had bad experiences trying to do any file operation with PII hardware. These are machines with >2GHz processors and 2GB of RAM. I don't think it's a resource issue there.

[OpenAFS] LiveCD for openafs disaster recovery scenarios ?
Hello At least one (and possibly two) hard disks on the machine (has RAID 5 - rebuild did not help too much) that runs our openafs cell failed today. This is a Debian machine. Partition /usr is down and attempts to mount it fail with bad superblock messages. As a result, all network and many other system commands (awk, etc.) are inaccessible. Now, is there a live CD that can be used to run the machine so that the users can at least copy over their data ? I think a reinstall is indicated. The two partitions housing /vicepa and /vicepb are not affected. Is there a way to retrieve data directly from the hard disks ? Thanks. ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info

RE: [OpenAFS] AFS and PhotoShop interaction?
What kind of files, jpg or tif? Here using 1.5.10 talking to a 1.4.0 server, the jpg are instantaneous, the tif take a little longer to make thumbnails of. Files are hi res 5+meg each. Drag and drop in both cases is just great. I just sorted through several thousand photos for a talk and the performance is superb. Using 1GB Lan. On the net with 768K upload, performance is slower until the cache gets built, then its just fine too. Same when on a 10BT wireless at a hotel.
