Hi Jason:
The decrease happened on both the local sata hba and the ISCSI
target. I will look into vmfs utilities. Thanks for your suggestion.
It's a miracle that this happened before going into production.
Luckily I could restore the mail server (zimbra network edition)
without loosing a single message.
Thanks again
Richard

Does ESXi provide a way to scan a LUN for a damaged file system? If
you saw a significant decrease in performance it could be that there
was something wrong with VMFS.

Subject: [OF-users] Esxi can no longer mount vmfs volume hosted on
ISCSI lun
Hi:
I am at a pre deployment stage. I setup an Openfiler ISCSI target,
with file io and and writeback cache. I am connecting 1 ESXi host ,
and 5 vm's were hosted on the ISCSI volume.
Today I noticed a dramatic slow down in disk speed. The esxi host
was getting 13 mb/s (it used to be 120 mb/s) with hdparm. This
happened with both local and ISCSI storage.
Therefore I stopped the vm's and rebooted.
Upon reboot , the vmfs volume on the iscsi LUN is not longer
recognized by ESXi.
The ISCSI session is initiated, the target is recognized, but the
vmfs volume doesn't mount.
Any idea how to go further
Thanks in advance
