ReadyNAS 4312 (or similar) - RAID config and expansion
Hi, I need help with a decision. We'd like 20TB of storage for both iSCSI LUN HyperV VHD virtualisation and general SMB3 data (with snapshots). One volume. The 12 bay RR4312S is a model we are familar with. We'd like the space to be easily upgradable in the future - cost is a consideration right now or we'd use bigger disks right away. We want to use RAID10. Is RAID10 an XRAID option? Whenever I've tried on the online calculator XRAID RAID 6 is chosen each time. So, if RAID10 isn't an XRAID option what do I do? Which is the best suggestion for populating it now with an eye on the future (4 years hence) in terms of expanding Flex Raid. Is Vertical less hassle than Horizontal? Therefore should we fill all 12 bays now then add bigger disks one by one in the future - i.e. vertically? Or do we leave chassis space for a horizontal expansion? Many thanks, Andy.

Dual RR4312X replacement for Multiple desktop NAS models - best RAID Level /Hard drives to use?
we own multiple desktop readynas boxes of different drive sizes (see photo) and are looking to consolidate into 2 new RR4312X models that will be located in 2 different offices with the idea of Nightly replication/Rsync (data identical -users access their local NAS) Currently the NAS support 40TB each (about 27TB used 12TB Free) Raid-6 on 8 bay 528X/628X with 2 EDA500 (different volume) for a total of 12 bays each.. For the new 4312X We are debating if we should just continue using RAID6 with the nightly replication or if Raid50/60 would be a better choice for performance given the nightly replication between NAS boxes (Raid10 takes away too much capacity) The other issue some of the hard drives are older (anything under 4TB has a few ATA errors & only shows a few timeouts during rebuilds) We are also trying to figure out the best way to expand the capicity of both of the new NAS servers to the same storage space (taking into account the HD's we already own) for example would it be better buying more lower cost 6/8TB given our current configuration - instead of fewer 12TB etc. thanks

Readynas 102 restarts services constantly - unable to access data.
My ReadyNas 102 running firmware 6.7.4, seems to be constantly restarting services. I'm sometimes able to see the shares... sometimes even get a few files..., but then it "disappears" and the network location is gone. ... until a minute or so later. Even the web-ui ... I'm sometimes able to see the status-screen before it jumps back into a loading-page waiting for the ui to become responsive again. I've tried reinstalling the OS, but it didn't work. I was thinking about flashing new firmware, but that requires the services to be open long enough for the process to finish.... Is it possible to connect the drive to a computer - windows or linux... and get the data through USB? The drive seems to be ok, although; It's the remains of a degraded RAID-1 setup. Thanks for all advice..

RAID 1 Issue - Volume Degraded after HDD replacement
I hava ReadyNAS 104 with firmware 6.6.1. Inside it I had 1 TB, 1TB, 3 TB and 6 TB HDDs, the two first configured as RAID 1. I had a RAID 1 with 2 HDD of 1TB, but one of them stop working. While I receive a new one, a replace the broken one with a 2 TB HDD (I know I'm loosing 1 TB of space). It was detected as part of the RAID 1, and started syncronizing. After it was sincronized, the HDD status change from SYNC to ONLINE, but the volume status is DEGRADED. I think the problem is that the 2 TB HDD is set as SPARE instead of ACTIVE SYNC. If you get the raid detail you see that there are 2 working devices, but only 1 active devices. As you can see, the status is clean,degraded. # /sbin/mdadm --detail /dev/md125 /dev/md125: Version : 1.2 Creation Time : Thu May 28 13:29:45 2015 Raid Level : raid1 Array Size : 971912832 (926.89 GiB 995.24 GB) Used Dev Size : 971912832 (926.89 GiB 995.24 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Tue Apr 25 09:51:21 2017 State : clean, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 Name : 2fe53622:Personal-0 (local to host 2fe53622) UUID : e9cdfd26:c97e9f56:51e0ac36:3c2bb179 Events : 116364 Number Major Minor RaidDevice State 0 8 51 0 active sync /dev/sdd3 2 0 0 2 removed 1 8 67 - spare /dev/sde3 Can anyone help me?

Recover from BTRFS RAID
Hello all After attempting all official methods to revive a Netgear RN-102ND NAS, I've removed the single WD 3TB Green drive to recover its data. Slaving it to a Windows PC, I open a popular program around here called Sysinternals Linux Reader for recovery. However upon attempting to open a partition for reading, a dialogue appears stating "can't open disk: Btrfs Volume 1 (0e34c953:data, raid) Check the disk and try again". SMART attributes are good, but I am about to run a bad sector scan. Can anybody shed any light on whether this has occured to them and what they did to overcome (if at all)? Richard
