Applies to:
Solaris Cluster - Version 3.2 U3 to 4.4 [Release 3.2 to 4.4]Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)
Goal
Prerequisite:
The following objects are required for global device filesystem to mount at boot time.
The following objects are required for global device filesystem to mount at boot time.
- Every node in Solaris Cluster must have a directories to mount global devices. Each node must have the following directories:
drwxr-xr-x 5 root root 5 Mar 11 2019 node@1
drwxr-xr-x 5 root root 5 Mar 11 2019 node@2
...
drwxr-xr-x 2 root sys 2 Mar 11 2019 node@64
There are maximum of 64 nodes in Solaris Cluster. The nodeid may be found in /etc/cluster/nodeid. All directories should be present. - Global device filesystem
- Each node in cluster must have a file "/.globaldevices".
-rw------T 1 root root 1073741824 Sep 22 07:43 /.globaldevices - If this is a fresh install of Solaris Cluster 4.4, then this filesystem is built on root pool on each node. The number at the end of the filesystem name corresponds to nodeid.
# zfs list | grep global
rpool/ROOT/solaris114-osc44/globaldevices_1 106K 40.9G 1.21M /globaldevices_1
This document will show how to fsck a global devices file system of Solaris Cluster mouted with lofi.
Verify that lofi devices are being used for the /global/.devices/node@<nodeid> file systems.
