Aug 09 21:37:23 <Cubber> I just installed SlugOS_BE on my NSLU2, I set it up so it boots from an NFS share, however I am having an issue setting up the swapspace after the reboot.  I get the following error when I run swapon -a
Aug 09 21:37:27 <Cubber> swapon: /swapfile: Invalid argument
Aug 09 21:38:46 <mwester> Do you have the correct syntax in your fstab for the swapfile?
Aug 09 21:39:30 <Cubber> yes I added: /swapfile swap swap defaults 0 0
Aug 09 21:40:06 <Cubber> I made the swapfile with the following command: dd if=/dev/zero of=/swapfile bs=1M count=128
Aug 09 21:40:13 <Cubber> then did swapon /swapfile
Aug 09 21:40:36 <Cubber> er I did mkswap /swapfile first then the swapon /swapfile
Aug 09 22:13:46 <Cubber> interesting message from /var/log/messages
Aug 09 22:13:49 <Cubber> Aug  9 18:12:14 (none) user.err kernel: swapon: swapfile has holes
Aug 09 22:17:49 <Cubber> I get that error every time I issue the swapon -a command
Aug 09 22:32:06 <jones_> is the swapfile over nfs?
Aug 09 22:33:35 <Cubber> jones_ yes sir
Aug 09 22:33:41 <Cubber> that is what I am trying to reasearch now
Aug 09 22:33:47 <Cubber> but finding no answers
Aug 09 22:34:40 <jones_> can't say i know anything that would help
Aug 09 22:35:06 <Cubber> would I be better off just using a flash stick for swap, or do I even need swap?
Aug 09 22:35:51 <jones_> imo a flash drive would definitely be better
Aug 09 22:36:13 <Cubber> I was hoping to save the ports though and go diskless
Aug 09 22:42:03 <jones_> by all means go ahead and see if it works good over nfs
Aug 09 22:43:41 <Cubber> hehe well right now it does not work at all
Aug 09 22:48:24 <mwester> IIRC, swapping over nfs is not a good idea -- there has been much discussion about the evils thereof, and I'm not sure what the final position on it ever was.  In any case, I don't think SlugOS does anything to disable it -- but I do think you need to do something to make it work over NFS.  Perhaps you need to do the mkfile on the host system?
Aug 09 22:48:45 <Cubber> tried that
Aug 09 22:48:57 <Cubber> trying a flash drive now
Aug 09 22:49:01 <Cubber> getting the same error
Aug 09 22:49:37 <Cubber> I just wiped the drive in fdisk created a new partition that was type 82 (Linux Swap) then did mkswap and swapon /dev/sda1
Aug 09 22:49:44 <Cubber> got swapon: /dev/sda1: Invalid argument
Aug 09 22:50:25 <Cubber> reboot got the flash stick to take
Aug 09 22:50:32 <mwester> How odd.  BTW what version of SlugOS is this?
Aug 09 22:50:41 <Cubber> newest just downloaed today
Aug 09 22:50:54 <Cubber>  cat /proc/version 
Aug 09 22:50:54 <Cubber> Linux version 2.6.27.8 (slug@builder) (gcc version 4.2.4) #1 Sat Mar 7 02:47:23 UTC 2009
Aug 09 22:51:27 <Cubber> I think cause the kernel was using the old partitions from the flash drive after the fdisk and I needed a reboot for that to take
Aug 09 22:51:36 <Cubber> everything I have found on the net about NFS says it can't be done
Aug 09 22:52:07 <Cubber>  Swap:       777440            0       777440
Aug 09 22:52:11 <Cubber> thats what comes up in free now
Aug 09 22:52:15 <Cubber> its a 1G flash stick
Aug 09 22:52:26 <Cubber> rest of the root is on NFS
Aug 09 22:54:59 <mwester> Yeah, the problem, as I recall, is that part of the NFS code can be paged, so it is entirely possible for your swap space to be unable to be paged back in because the code that would do that is, itself, paged out.
Aug 09 22:55:54 <Cubber> well I was using the flash drive for unslung before but after I found out I could thin client them I wanted to use NFS so the flash drives are free for swap usage I guess.
Aug 09 22:57:44 <jones_> did you see the page on this subject on the wiki
Aug 09 22:58:06 <Cubber> no I looked around but just found info on how to create the swapfile nothing about nfs issues

Aug 09 22:58:29 <jones_> ✍http://www.nslu2-linux.org/wiki/HowTo/MountNFSSwapPartition
Aug 09 22:58:31 <Cubber> was what I mainly used
Aug 09 22:59:14 <Cubber> ohhh
Aug 09 22:59:17 <Cubber> that makes sense
Aug 09 22:59:21 <Cubber> mount it then swap on the mount
Aug 09 22:59:24 <Cubber> so it is local
Aug 09 22:59:46 <Cubber> will have to give that a try
Aug 09 22:59:49 <Cubber> thanks
Aug 09 23:00:09 <mwester> sneaky
Aug 09 23:00:25 <jones_> do tell if it works
Aug 09 23:00:44 <Cubber> yupper
Aug 09 23:05:05 <Cubber> hanging on the mount
Aug 09 23:06:14 <Cubber> just gonna stick with the flash drive it will be faster anyway than swaping over the network
Aug 10 00:07:12 <Cubber> lsusb returns nothing?
Aug 10 00:09:45 <Cubber> cd
Aug 10 00:09:48 <Cubber> cd
