I have two 1.5TB formatted ext2 JBOD. They show up in disk management as:
1 NAS-HDDB Seagate ext2 1405473 100% free
2. HDDA Seagate ext2 1408337 100% free
However after mapping the NAS as a drive in Windows Explorer the properties only show 1.27 TB available - so a whole drive of storage is missing.
Is something wrong? How do I verify that the storage on both drives is available?
If all is well, how does is the JBOD storage allocated - e.g. does it fill one drive first and then fill the other?
I plan to use this as a backup drive, so I would rather have more space than the redundancy of RAID 1. Similarly the fact that a single drive failure in RAID 0 kills the data on both disks makes the speed benefit unattractive (same for RAID linear).
Can someone give me some guidance here?
