options raid.disk.timeout.enable

Can someone tell me what this setting does.  I have read bits and pieces about the setting but nothing as to what its function is exactly.

Re: options raid.disk.timeout.enable

Hi johnhuber,

I think there is no setting like  options raid.disk.timeout.enable (AFAIK)

The options associated with raid.disk are

options raid.disk.background_fw_update.raid4.enable

options raid.disk.copy.auto.enable

options raid.disktype.enable

The nearest one will be the below one.

options raid.timeout

The raid.timeout option controls how long a storage system runs after a RAID group goes into degraded mode or the NVRAM battery malfunctions or loses power. You can change the value of this option.

Refer this doc for the additional info

Hari.

The option is there up until 8.1.1.  It's undocumented though.  Starting from 8.1.2 the option is no longer there, or is otherwise invisible.

My best guess is that it's a list of drive types where the raid.timeout is enabled for.  But that's just a WAG.

Re: options raid.disk.timeout.enable

The setting does exist.  It is a hidden setting, forgot to mention that.  I got an ASUP risk assessment on it and I modified the setting.

The page above gives a very limited description of the setting and I was looking for more detail on the option.
