<nehemiah>
My clients don't boot on a new LTSP installation with LVM on the server. The client show a lot of errors with 'lvmetad' in there and then drops to BusyBox. Any direction in how to fix this?
13:41
<alkisg>
Inside that busybox, what's the output of cat /etc/fstab?
13:42
<nehemiah>
No output at all
13:43
<alkisg>
What's your server's /etc/fstab?
13:45
<nehemiah>
https://pastebin.com/FiE1S7ui
13:47
<alkisg>
nehemiah: on busybox, type: cat /root/etc/fstab
13:47
Does that show about the same as your server fstab?
13:48
<nehemiah>
Hmm, no such file it says
13:49
<alkisg>
!nbd-client
13:49
<ltsp>
nbd-client: To try mounting the NBD image from the client initramfs: nbd-client 192.168.67.1 -N /opt/ltsp/i386 /dev/nbd0
13:49
<alkisg>
Does that ^ work?
13:49
Replace the server ip and maybe i386 with amd64
13:51
<nehemiah>
No, it fails with a bunch of I/O errors and then it says: nbd0: unable to read partition table
13:52
<alkisg>
That sounds like success to me
13:52
Next try: mkdir /nbdmount; mount /dev/nbd0 /nbdmount; ls /nbdmount
13:52
Do you see the virtual disk contents there?
13:55
<nehemiah>
Again I/O errors and then mounting /dev/nbd0.... failed: invalid argument
13:56
<alkisg>
On the server, what's the output of ls -l /opt/ltsp/images ?
13:56
<nehemiah>
https://pastebin.com/ZJVSR2Rj
13:58
<alkisg>
and the output of this? grep -r . /etc/nbd-server
13:58
<nehemiah>
https://pastebin.com/CEtk4GPu
13:59
<alkisg>
Seems ok; did you put amd64 in the command: nbd-client 192.168.67.1 -N /opt/ltsp/amd64 /dev/nbd0 ?
14:00
Also try with nbd2 instead, i.e. nbd-client 192.168.67.1 -N /opt/ltsp/amd64 /dev/nbd2
14:00
...in case nbd0 was already in use
14:02
<nehemiah>
That seems to work
14:05
<alkisg>
did you end up seeing the contents in /nbdmount?
14:05
<nehemiah>
Okay I've got /dev/nbd2 mounted on /nbdmount and I see the virtual disk contents
14:05
<alkisg>
If yes, check the result of cat /nbdmount/etc/fstab
14:05
Is it the same as the servers?
14:06
<nehemiah>
# UNCONFIGURED FSTAB....
14:07
<alkisg>
That sounds strange then, I was assuming it would be https://git.launchpad.net/ltsp/commit/?id=6db709c8df69132465b7704c20b1fb3c7f182141
14:07
I'd need to see it with remote support then, sorry, can't help over IRC
14:08
<nehemiah>
Sure
14:20
Should I enable something in remote assistant in Epoptes?
