Hello Community,
I’m about to invest in a NAS system and with the Ex4 as a most probable option so far i’d like to clear some doubts that I couldn’t clear so far, and I’d apretiate if you’d help me with that.
The questions are:
-
If i establish a RAID5 with 5 disks and after decide to add a 4th disk will it be acknoledge by it and be setup default to JBOD or do i need to reconfigure everything again with the previous RAID5 defined disks needing to be formated ?
-
If the system is holding a 2 disk RAID1 format, if I add 2 more disks do they go to the same format and i get another independent RAID1 protected disks or another thing may happen ? And again is the re-setup mandatory for it to be working with the added disks ?
-
Let’s say i have only a single 4TB disk setup as JBOD and decide to transform it to a RAID5 3 disk. So for that i buy 3 more disks so that the first disk has the information in case something may go wrong. Does the Ex4 have the ability to copy the information existing in the 1st disk and distribute it to the others internaly without having to retrieve the 1st disk and needing to use other system other than the NAS itself.
-
Once a RAID is setup (the RAID5 for ex) and in a 3x4TB disk setup i decide to use only 9TB total and leave 3 for other use, the other 3 are setup as JBOD, Spanning as 1 Volume, unused or I may choose how to configure it ? I’ve read in the manual that it may be created a spare disk or configure the remaining disk space as Spanning but doesn’t say anything about JBOD.
Thank you for your consideration and I’d apretiate a answer as soon as possible since I need to make a decision soon and wanted to make a right one knowing these topics
Once again thank you,
