January 16, 201610 yr Hi, I currently have a 4 drive array in unraid, I'm looking to replace one of the drives with a much larger one. The array doesn't have a parity device currently. The drive i want to remove has nothing stored on it, however if i pull it and try and rebuild the config will I lose all my drive mappings and data? I could potentially try and mount another drive through a USB bay and build a parity first but want to avoid this if possible.
January 16, 201610 yr Community Expert Without a parity drive you can just stop and change anything. Nothing will be lost. You really should get parity going though. And you should have backups of anything important even if you have parity.
January 16, 201610 yr Community Expert Although you’re not using parity, you can’t replace one data disk with another, you have to go to tools and do a new config, then just re-assign all disks you want to use now.
January 16, 201610 yr Author New config doesn't lose data then? I can just remap my array? Don't worry nothing at all important on this server.. Just one i toy around with!
January 16, 201610 yr Community Expert New config doesn't lose data then? I can just remap my array? Correct. As long as the drives were previously used by unRAID then after a New Config they can be assigned again and the data remains intact.
January 16, 201610 yr Author Perfect, many thanks. Knew it was going to be easy just couldn't see it for looking! Update: For anyone else doing this in the future, went ahead no problems. Didn't even lose any of my shares or drive mappings in dockers/VM's so was as easy as could be! Gotta love unraid.
