  • 1.  Duplicate name 'slotsfile' entry in cache

    Posted Sep 13, 2023 11:38 PM

    Storage upgrade caused some disruption to datastore hosted in our environment. We ended up restoring servers from a day prior to the outage. Since that outage, we see this error logged in all ESXi host in that cluster.

    Duplicate name 'slotsfile' entry in cache. (2023-09-13T23:30:47.617Z cpu6:2099255)

    I see this event constantly logged in all our Esxi host.

    Hi,

    If you had SIOC enabled on datastores before disruption, try to disable and remove slotsfile manually.

    The re-enable SIOC again.

    Thanks Davoud. You certainly guided me in the right direction. I found out the datastore that is triggering these alerts.

    Removing slotsfile manually didn't fix the issue for me, but i am going to get rid of that datastore and provision a new one.

    Hi,

    I have the same problem, disabling SIOC and manually deleting the file did not help. When I turned off SIOC on LUN, the alerts disappeared from the logs. I manually deleted "slotfile" then turned on SIOC and alerts appeared again.
