Hi,

I'm getting an error 'No such device' when I try to save from the  
evmsgui, so I'm having trouble moving on to setup snapshotting - my  
main reason for moving to EVMS.

I've just started to use EVMS after having previously used LVM2 at a  
very basic level (to provide volumes for the xen guests on this  
machine). I'm running Debian 3.1 (against testing repositories) with  
a Xen 3.0.2 kernel (this system is the dom0). It's a 2.6.16-xen  
kernel which has been patched with the bd-claim patch. I've taken on  
all the engine patches for 2.5.5 prior to compiling the tools. The  
LVM2 volumes aren't mounted by me - they're used exclusively by Xen,  
so I've modified /etc/evms.conf from the default installed when I  
compile evms-2.5.5 so that I have:
activate {

         # Names of volumes and objects that should be activated.
         #
         # Names can be specified using "*", "?", and "[...]" notations.

         include = [ * ]

         # Names of volumes and objects that should not be activated.
         #
         # Names can be specified using "*", "?", and "[...]" notations.

         exclude = [ /dev/evms/lvm2/Storage/* ]
}

(Storage is the only container currently defined)

Quick check on my understanding of how things work: Am I correct  
excluding those volumes because I'm not going to mount them i.e. I'm  
just leaving them to Xen as is?

I'm using evmsgui until I understand things a bit better (so, if you  
need me to run any of the CLI utilities I'll probably need quite  
explicit instructions) and when I try to do a save I'm getting an  
error 'No such device'. When I look at the /var/log/evms-engine.log  
I'm getting a lot of errors. If it's useful, I can mail the entire  
log file but for now, I'll try to pick out the unique error messages.

At the start I'm getting:
Mar 02 00:25:00 eire.igallagher.com _5_ Engine:  
load_module_plugins:   short name:  SWAPFS
Mar 02 00:25:00 eire.igallagher.com _5_ Engine:  
load_module_plugins:   long name:   Swap File System Interface Module
Mar 02 00:25:00 eire.igallagher.com _5_ Engine:  
load_module_plugins:   version:     1.1.13
Mar 02 00:25:00 eire.igallagher.com _3_ Engine: do_fork_and_execvp:  
execvp() failed.  errno is 2: No such file or directory
Mar 02 00:25:00 eire.igallagher.com _5_ Bad plug-in pointer: try_run:  
mkdosfs completed with exit code 2.
Mar 02 00:25:00 eire.igallagher.com _3_ Engine: do_fork_and_execvp:  
execvp() failed.  errno is 2: No such file or directory
Mar 02 00:25:00 eire.igallagher.com _5_ Bad plug-in pointer: try_run:  
dosfsck completed with exit code 2.

And similarly for fatresize, mkntfs, ntfsfix and ReiserFS - I'm not  
using any of these so I'm making (shout at me if I'm wrong here!) an  
assumption that I can ignore these for the time being.

When I do my save, I'm then getting a series of 'Change pending'  
messages which then produce errors (for all the pending changes):
Mar 02 00:31:38 eire.igallagher.com _5_ Engine:  
is_volume_change_pending: Change pending: Volume /dev/evms/hda1 needs  
to be activated.
Mar 02 00:31:38 eire.igallagher.com _5_ Engine:

to be activated.

19 activating object lvm2/Storage/Home: No such device
Mar 02 00:31:38 eire.igallagher.com _2_ Engine: run_command_v4: Error

Mar 02 00:31:38 eire.igallagher.com _3_ Engine: activate_object:  
Error code 19 activating object hda3: No such device
Mar 02 00:31:38 eire.igallagher.com _3_ Engine: activate: Error code  
19 activating object lvm2/Storage/donegalDebian31home: No such device

These messages are repeated for the remainder of the volumes I have  
in the 'Storage' container. At this point I'm not continuing to try  
and set up the containers that I'll use to do snapshots until I  
resolve these errors.

In /var/log/messages I'm also seeing errors like:
Mar  2 00:25:01 eire kernel: hdc: packet command error: status=0x51  
{ DriveReady SeekComplete Error }
Mar  2 00:25:01 eire kernel: hdc: packet command error: error=0x54  
{ AbortedCommand LastFailedSense=0x05 }
(The incidence of these messages seem to correspond to the times  
during today that I used evmsgui.)

Thanks, for taking the time to read this far - sorry if I waffled on.  
If you could give me any suggestions, links to pages I should read (I  
haven't been able to turn up anything on Google that I'm able to use,  
thus far) or help I'd appreciate it.

Cheers,
James
