I have a server with a huge number of datasets (around 9000)
When the pool containing the datasets is imported on boot up, a few (<10)
datasets are not mounted and thus not exported via nfs. Which dataset is not
mounted is random.
All datasets are exported via nfs. A zfs import takes around 30 mins.
The system is running s10u4
sunsystem9:[~] > uname -a
SunOS sunsystem9 5.10 Generic_127112-10 i86pc i386 i86pc
The zpool configuration is as follows:
sunsystem9:[~] > zpool status
pool: private
state: ONLINE
scrub: none requested

errors: No known data errors
The disks are on a ST6140 attached to the system via redundant fc
(multipathing) (Each of the disk devices are volumes with 5 500gb disks in a
raid5)
Any ideas?
