Hi, we are using a SLES10 Patchlevel 3 with 12 Nodes hosting tomcat application servers. The cluster was running some time (about 200 days) without problems.
Recently we needed to shutdown the cluster for maintenance and experianced very long times for the umount of the filesystem. It took something like 45 minutes each node and filesystem (12 x 45 minutes shutdown time). As a result the planned downtime had to be extended ;-) . Is there any tuning option or the like to make those umounts faster or is this something we have to live with? Thanks for your help. If you need more information let me know. Marc.
