Known problems and workarounds
This section describes the list of known problems and workarounds for the HP Serviceguard toolkit
for NFS A.12.00.00 on Linux. However, this is subject to change without notice. For the latest
information contact your HP support representative.
• During a package failover, the NFS server might receive status information messages such
as:
◦ Input/output error
◦ Stale NFS file handle
◦ Write error: Stale NFS file handle
Workaround: Try to remount the NFS shares at the client side.
• If the package fails over during a user file access, the client node might experience a
momentary hang.
Workaround: No manual steps are required. Access mount point continues as soon as the
package completes failover to the other node.
• The NFS client might not receive a crash event notification when it sends an initial lock request
to the NFS server. If the NFS package fails over to an adoptive node, before the client entry
in /var/lib/nfs/statd/sm directory is copied to the package holding directory, the client
node might not reclaim the lock.
The probability of this occurrence within the default time interval between copies is extremely
low as the status monitor file copy interval is very short (by default, five seconds).
Workaround: You can reduce the probability further by configuring the time interval to a value
lower than the default value in the package configuration file.
