Hey All,
I've changed the size of /mnt/luns/san-luns/host01-disk01.img on disk.
Now I would like to change the size visible in targetcli. How could I
do that?
/backstores/fileio> ls
o- fileio
......................................................................................................
[4 Storage Objects]
o- host01-disk01.img ........................................ [2.0T,
/mnt/luns/san-luns/host01-disk01.img, in use]
/backstores/fileio>

Thx,
TK.

I've managed to change the size by deleting the fileio object and
recreating it in the absence of a way to resize without having to do
that. But did run into an issue with targetcli:
You may run into this error:

When does this happen?
When deleting a LUN and readding it with greater size, it doesn't really
update the config file on disk and is thereby possibly unable to add the
new LUN under the old name?
/qla2xxx/21:0...81:81:21/luns> ls

Moreover, when REcreating the /backstore/fileio/, the new disk
disappears without apparent reason:
/backstores/fileio> create mdskvmp02-d01.img
/mnt/HTPCBackupXFS/san-luns-scst/mdskvmp02-d01.img 4T

(We are not in the configure mode btw) Noticed in the static config
file on disk that hasn't been saved yet, that the old entry still exists
despite removing it from above. Not sure if that matters though:
[root@mbpc-pc target]# view scsi_target.lio
disk mdskvmp02-d01.img {
buffered yes
path /mnt/HTPCBackupXFS/san-luns-scst/mdskvmp02-d01.img
size 4.0TB
wwn e85336b5-2c9b-42c0-985e-b62b10bdce6f
attribute {
So exited, waited a few minutes and reentered targetcli and recreated
the entries with a higher size. At this point, the error disappeared
and we were able to save again. The underscore under the LUN's section
also disappeared. The final result was a clean save:
