I have a couple cheaper Lenovo IX2 2-disk NAS devices.  First of all, there is NO hardware failure, including disk.  I had a power jolt and one IX2 was on a dead UPS and dropped and came back a couple times, which was enough to corrupt the IX Linux OS.  Because this is a NAS that is copying it's opt read only at boot every time and already was a super pain just to edit running config or install optware etc., I have no issue simply rebuilding it from an old config.ISSUE Symptoms:Much running config seems lost, web GUI indicates a factory reset/restore is needed.HOWEVER - ONCE I MANUALLY MOUNTED THE RAID POOL using the other working IX2 as a template of things to look at, the good news is ALL USER DATA IS IN TACT AND NO RAID ERRORS EXIST.  (This is RAID0, so I would be totally SOL if there were, I fully realize that).Because the data IS all there is the only reason I am working this hard (but it really shouldn't be).The key here is some user data, but then I had a 2tb iSCSI volume on this IX, being used 100% for VMware.  This iSCSI volume file is also in tact.  This, being my datastore is really what I am after.WORK ALREADY COMPLETED:I have unboxed a brand new 4tb WD USB3 drive (albeit only USB2 on the IX2), plugged it in, and used mkfs to reformat the default partition as EXT4.  I then mounted it as /dev/usb and began this command, roughly 20 hrs ago already:rsync -axHAWXS --numeric-ids --progress /mnt/pools/A/A0/ /mnt/usbYes, I now see that because I initially tried the newer info:progress2 and it did not work, that I merely quickly edited the cmd and forgot to add the friggin -P for partial.  That is one question, I would really like to kill this and restart it, can I still use --append having forgotten to use --partial originally?  How can I force a continue and AVOID losing this 20+hrs if I need to restart now?  (This is an optional portion of my question)I ran the rsync specifically for the progress and checksums and restart ability fully knowing it was much slower than standard cp - but this IX2 always sucked but I could push reads over the 100mbit to 50-65MB/s via iSCSI, yet this rsync is averaging ~10MB on the iSCSI 2tb file.  It's absurd and it is estimating 3 more days.  GOAL:My ultimate goal (and question here) is how to abandon this old IX2 hardware and move the disks and get them mounted on newer PC running a newer Linux distro at full SATA3 & USB3 in hours not days.ADDITIONAL DETAILS:Command output for fdisk -l:root@ix2b:/mnt/usb/iSCSI# fdisk -lWARNING: GPT (GUID Partition Table) detected on '/dev/sda'!
