- Thanks very much to everybody who replies to this article I posted a few days
- ago.
-
- The problem is not yet completely understood, but it seems to be related to
- the fact that all our disks are shadowed. The satellite keeps a lock on a disk
- and prevents the reboot of the boot host. We are still with SHADOW Phase I.
- This problem is solid and occurs at every reboot of the BOOT host.
-
- By luck, the problem does not occur if there are more than one disk server in
- the cluster. So, we find a workaround!
-
- However, I would appreciate any new information on the subject.
