I lost power last night and cant get my array to start looking at the log i think it is my cache drive, but i dont know how i can get it mounted to copy files off of it or what i can do any help would be appreciated. included diagnostics bundle but i dont know how helpful it will be with the server getting stuck and unable to export diagnostics once i have attempted to start the array

See if it can be imported read only before starting the array:

zpool import -o readonly=on cache

If it works backup and re-format

do i type that in the terminal in the web gui or how do i start that?

 

that kind of worked i got as much data off of it i could. i still lost a couple hundred gigs of downloads and some application conffigurations that i set yesterday but. im back up and running thank you for your help
