ReadyNAS 2304 add and remove drive in JBOD mode
Hi, I have my ReadyNAS 2304 with inside one 4 TB drive (with XRAID activated and JBOD mode). I would like to remove this 4 TB drive to use it in another ReadyNAS I use for other purposes with just a ...

I was thinking that one way to proceed could be this one:
- insert the new drive in a free bay of the ReadyNAS 2304 and wait until the end of the synchronization;
- remove the 4 TB drive from the Readynas 2304;
I think at the end of the process I could have a space bigger than before and equivalent to the size of the new drive (with XRAID activated and JBOD mode).
Am I right or the entire process will not be that simple?
Thank you for your help
It's not that simple. You'll end up with a degraded 4 TB volume if you use that process.
You could
- power down both the 2304 and your RN102
- remove the disk(s) in the RN102 - labeling by slot so you restore them properly later on.
- put the 4 TB 2304 drive in the RN102, and power up. It should boot.
- do a fresh install with the new disk in the 2304.
- copy back the files using ReadyNAS backup jobs.
- power down the RN102 and restore the original disk(s)
Alternatively,
- change to flexraid on the 2304.
- create a new jbod volume with the new disk, and copy the data to it with ReadyNAS backup jobs. Put any home folder data into a public share on the new disk temporarily, and uninstall any apps.
- export the 4 TB drive and then remove it.
- reinstall your apps, and repopulate the home folder data if needed.
Either way, I would recommend backing up your data, as disks (and NAS) can/do fail at any time. Plus there is always some risk of mishandling (accidentally dropping a disk for example).
Hi Sandshark,
thank you for your detailed answer.
I don't think I feel brave enough to try the last way you explained (the much more complicated method using SSH). I use sometimes SSH but I don't feel confortable enough with it, compared with it I would prefer to reconfigure the entire NAS again. Thank you anyway to show me that a more direct way exist if I want to follow it.
I would have some more simple question about your answer:
- you wrote "so long as you have the backup "just in case". that's the best direction"; do you mean that in any case, if I experiment any problem with the new drive and the new configuration, I just have to switch off the NAS, take off the new drive, insert the old one (that before I took off and left untouched on the table) and when I'll switch on the NAS again I'll find the complete old situation restored (configuration, users, shares, data, ecc.)?
- you wrote that you don't think restoring a configuration file will work, since the new volume will have a new name; my plan is to give the new volume the same name than before, do you think if I pay attention to name the new volume with the same name of the old one I'll have the possibility to restore the saved configuration?
OK, I tried to go ahead with my process with a fresh installation and now I can write here the answers to the question I asked in the previous post:
- In any case, if I experiment any problem with the new drive and the new configuration, I just have to switch off the NAS, take off the new drive, insert the old one (that before I took off and left untouched on the table) and when I'll switch on the NAS again I'll find the complete old situation restored (configuration, users, shares, data, ecc.)? Yes, it worked in this way, I fresh installed the new drive and, just to try, after that I removed it and insert again the old one: I could find the same configuration, files, everything I as it was before I started.
- Restoring a configuration file will not work, since the new volume will have a new name. Yes it was true, I couldn't find a way to set the volume name during the new fresh installation (it was automatically set as "data") and, after that, when I tried to restore the configuration the system didn't allow me to to it (I tried both the "everything option" and the "custom option deselecting the share access flag" but didn't work).
I thank a lot the people who tried to help me. Bye.

.
If this is still of interest - the trick here is to switch to flexraid, destroy the data volume, and then create a new one as jbod. The system will let you set the name for the volume you create.
