I wouldn’t normally call out new patch releases in my blog, but this one has an important fix for Virtual SAN users. As per KB article 2102046, this patch addresses a known issue with clomd. The symptoms are as follows:
-
Virtual machine operations on the Virtual SAN datastore might fail with an error message similar to the following:
create directory <server-detail>-<vm-name> (Cannot Create File)
The clomd service might also stop responding.
- Virtual SAN cluster might report that the Virtual SAN datastore is running out of space even though space is available in the datastore. An error message similar to the following is displayed:
There is no more space for virtual disk .vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking _Retry. Click Cancel to terminate this session.
The clomd service might also stop responding.
While the clomd issue is easily addressed by restarting the clomd service, consider deploying this patch during your next maintenance cycle to avoid this annoyance, or if you re considering a new VSAN deployment, definitely consider using this latest version of ESXi 5.5.
