Ok, it's about time I officially start this project again, as the last time I did, my empeg had a serial number of 00359.

The first step failed, running the client. Bug 3000 is filed, hopefully the client will be fixed soon.

Bug 3000

Dude, it told you what the problem is. CONFIG_SYSVIPC is not enabled in stock kernels.

Drakino - if dnet get a workaround for the SYSVIPC issue and provide a version which works for us, please let us know. I generally run it on most of my sgi boxes (for raw power) but it's definitely cooler to crack while driving

I know, but the older clients used to work fine, so it probably dosen't really need that to function. Talking on #Distributed, they seem interested in fixing it, hence the bug report.

The maintainer of the Arm Linux client responded to the bug, he's going to release a pthreads version, thus making it compatible with the empeg again.

I figure I'll set up the client similar to the way I did back on my Mark 1. The buffers will be held in a ramdisk, as the client enjoys frequently writing to them. Then, on a timeout, the buffers will be copied from the ramdisk to the harddisk. Any suggestions on the timeout? I think last time I used seven minutes, that seemed to be a good balance to catch the short car trips, and also infrequent enough that the disks shouldn't be in rw mode too often. The actual rw time back then was about 2 - 4 seconds not including spinup time, I'm sure now that could be a bit quicker. Also, I only rwed the one partiton I had the buffers stored on, not everything.

Are you going to set it up with something like a /dnet partition and just rw that? I wonder if this is also the kind of thing that ext3 could make even safer - I am just looking for some justification to go ext3 because I want to play with it but I really have no need to

Do you want a version of the kernel with SysV IPC turned on? It'll take 5 minutes for me to do...

No need, but thanks for the offer. I haven't had any time to look into this recently. By the time I do, the newer client will probably be out with the fix for the SysV IPC issue.
