Hi all, I am using Centos 5.2 for both DomU and Dom0. I used "xm block-attach" to attach a LV to a DomU and mounted to DomU''s /mnt. I tried to run "xm block-detach vm1 /dev/sdb", I find that this command will hold for long time as DomU has not umount /mnt. I have done an experiment by running "time xm block-detach vm1 /dev/sdb". I find that this command needs 1min 40s to timeout. Any method to shorten this timeout? [root@localhost] time xm block-detach vm1 /dev/sdb Error: Device /dev/sdf (vbd) could not be disconnected. Usage: xm block-detach <Domain> <DevId> [-f|--force] Destroy a domain''s virtual block device. real 1m40.149s user 0m0.052s sys 0m0.044s P.S. I tried xm block-detach vm1 /dev/sdb -force , this command will result hang of DomU.
