Re: [K12OSN] School K12Linux clients not able to complete boot after 50+ or so clients are up

Further to: I found some bugs reported in early versions of Ubuntu LTSP that referred to "swap causes connection loss" when using swap over NBD and squashfs. Could this apply here? What could we change to experiment with it? The Ubuntu bug was apparently fixed by noting that "the reason is that the SWAP nbd is using /dev/nbd0. So is the currently mounted /rofs which is a component of the / unionfs. The fix is to change the file to use /dev/nbd1." [R1]

Best, Daniel

It finishes the line "Eth0 link up, 100 Mbps, full duplex, etc." and the next line says:

Negotiation: Error: Server Connection Closed

Could that be where it's negotiating swap, and we've run out of swap space after 50 clients?

I tried powering off a client on the same server that had booted OK and seeing if the next one booted OK, but no luck, and further, the client that was OK that I powered off wouldn't finish booting now.

Any advice appreciated!  Daniel
