Hi,
it worked!
for reference...
on host where vm is running...
multipath -r
shows old size so I rescan both paths...
echo 1 > /sys/class/scsi_device/2\:0\:1\:62/device/rescan
echo 1 > /sys/class/scsi_device/2\:0\:0\:62/device/rescan
then...
multipath -r
=2E..shows new size
now I get lun_id (part of --path) and vm_id (--domain) from api and...
virsh -c qemu:///system blockresize --path
/dev/mapper/36005076b07500eff541809600000001c --size 629145600 --domain
7a5de3e0-ecbd-4ed6-bf98-2e7a45e96027
btw. size is in KiB, so in my case 600GiB * 1024 * 1024
I had to set sasl passwd for my user... I hope this doesn't break
something...
saslpasswd2 -a libvirt my_username
after this resize the colegue tell me that direct lun was resized on the
vm side...
[524704.451468] sd 2:0:0:1: Capacity data has changed
[525449.969906] sd 2:0:0:1: Capacity data has changed
[525449.971771] sd 2:0:0:1: [sdb] 1258291200 512-byte logical blocks:
(644 GB/600 GiB)
[525449.972697] sdb: detected capacity change from 536870912000 to
644245094400
I have no idea what could happen if I set wrong size :-)
Thanks, Jiri
