Default Re: Guardian OS units

Yes, it applys to all Guardian OS Units. It must be down to a single HD and capable of booting without any errors. I do not have NetVault running, so it may need disabling too, if it was shipped with your unit. If it encounters a problem it will drop into the recovery console. If you have the GSU, you can drop into the recovery console and do a clean install using the GSU. You will still need to swap your new drives in after using the recovery console for a clean install.

Some back ground. The GuardianOS is well design to recover from most any issues, by the use of snapshots and normal backups. AV causes a problem if it's not shutdown properly or have file corruption, preventing it from being shutdown. With snapshots disabled, it releases the drive info from flashram/bios. So it will not drop you into the recovery console during a cold boot. When a HD is replaced while powered down it will only transfer the OS, even if there is a raid structure. But then again you have a broken raid and it now knows the new drive, even though you did not hot swap it. Once the OS has been trasfered over, move the drive to position 1. hot swap the rest of your new HD in, once the disk leds go out your ready to build you new array.

If you hotswap drives you transfer the existing file structure over with the same capacity as the original drives, or new hd if clean. The reason for the cold boot file transfer is to get a clean system with only the OS.

It's always nice to have HD pre loaded with the OS, but you still must disable Snapshots and AV or it will drop you in to the recovery console.
