Description of problem: 1) /etc/xinetd.d/nbdswapd on server specify port 9572, but on client side usr/share/ltsp/ltsp-init-common specify default port 9210. Thus, without is port 9572 explicitly defined in lts.conf, NBD swap isn't working. 2) I must add some small delay (sleep 0.5) to /usr/share/ltsp/ltsp-init-common routine configure_swap after "modprobe nbd", else next command nbd-client for some reason fail: NBD_PORT=${NBD_PORT:-"9572"} modprobe nbd sleep 0.5 nbd-client $SWAP_SERVER $NBD_PORT /dev/nbd0 && .... Tested on 800MHz PIII/256MB thin client, on slower HW it maybe run OK... Version-Release number of selected component (if applicable): ltsp-5.1.7-2.fc9 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Thanks for the report. We will look into this. https://www.redhat.com/mailman/listinfo/k12linux-devel-list https://fedorahosted.org/k12linux/wiki/Meetings You might be interested to follow our development mailing list and weekly development meetings.
Here's an interesting problem: [root@newcaprica cups]# telnet 172.31.100.254 9572 Trying 172.31.100.254... Connected to 172.31.100.254. Escape character is '^]'. /usr/sbin/nbdswapd: line 23: /dev/stderr: No such device or address Connection closed by foreign host. Do you see this as well?
oh, sorry, it I resolved by changes (/usr/sbin/nbdswap): if [ -n "$SWAPDIR" ]; then if [ -d "$SWAPDIR" ] && [ -w "$SWAPDIR" ]; then - TEMPFILE_OPTS="${SWAPDIR}XXXXXX" + TEMPFILE_OPTS="${SWAPDIR}/swpXXXXXX" else and path to nbd-server is on Fedora diferent: # start the swap server -/bin/nbd-server 0 $SWAP $NBD_SERVER_OPTS -C /dev/null > /dev/null 2>&1 +/usr/bin/nbd-server 0 $SWAP $NBD_SERVER_OPTS -C /dev/null > /dev/null 2>&1 # clean up the swap file
And if I remember, directory "/var/lib/ltsp/swapfiles" (defined by SWAPDIR in /etc/ltsp/nbdswapd.conf) was owned by root:root, mode 755 (I'm not sure). But xinet daemod start /usr/sbin/nbdswapd as user "nobody", thus chown nobody:root /var/lib/ltsp/swapfiles chmod 770 /var/lib/ltsp/swapfiles
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
https://code.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk Please look over the changes I made upstream with are slightly different from your changes. This works for me. Will be in the next version pushed to updates.
This was fixed in Fedora 9 updates a while ago. You get 64MB NBD swap by default now. Edit /etc/ltsp/nbdswapd.conf to change the amount.
