Storage Foundation Cluster File System problems
■ If this error message displays:
mount: slow
The node may be in the process of joining the cluster.
■ If you try to mount a file system that is already mounted without –o
cluster option (that is, not in shared mode) on another cluster node,
# mount -F vxfs /dev/vx/dsk/share/vol01 /vol01
The following error message displays:
vxfs mount: /dev/vx/dsk/share/vol01 is already mounted,
/vol01 is busy, allowable number of mount points exceeded,
or cluster reservation failed for the volume
Command failures
■ Manual pages not accessible with the man command. Set the MANPATH
environment variable as listed under “Setting PATH and MANPATH
environment variables” on page 18.
■ The mount, fsck, and mkfs utilities reserve a shared volume. They fail on
volumes that are in use. Be careful when accessing shared volumes with
other utilities such as
dd, it is possible for these commands to destroy data
on the disk.
■ Running some commands, such as vxupgrade -n 7/vol02, can generate
the following error message:
vxfs vxupgrade: ERROR: not primary in a cluster file
system
This means that you can run this command only on the primary, that is, the
system that mounted this file system first.
Performance issues
Quick I/O File system performance is adversely affected if a cluster file system
is mounted with the qio option enabled and Quick I/O is licensed, but the file
system is not used for Quick I/O files. Because qio is enabled by default, if you
do not intend to use a shared file system for Quick I/O, explicitly specify the
noqio option when mounting.
