I can understand your situation and I know it will cost lot of extra money to just verify if it is NAS's hardware problem. I have already spent way too much time and money on this effort. If I have to do something, I will have to buy another NAS. Sorry, I can't afford to do the test you want. As I hit the problems, I replaced various disks with drives you now say are not valid for a test but Western Digital says are world class. As I had the Lockerstor 4, I decided to just add the AS6004U expansion not realizing that RAID groups could not span the two boxes. I realized after purchase that it was a mistake to have purchased the Lockerstor 4 and shoud have purchased the Lockerstor 8 or 10. I purchased the ASUSTOR Lockerstor 4 as a way to house the growing stack of drives I had and to be able to better manage my data. Your suggestion also means that I have to spend about a week copying data. All of these scenarios mean I have to spend money, over $1,000 to get where I wanted to be. If it works then I have proven the point, keep it, and ask you for replacements for my existing equipment. For less money I could replace the unit with an 8 bay QNAP QNAP TS-832PX-4G 8 Bay High-Capacity NAS with 10GbE SFP+ and 2.5GbE ( ) or an 8 bay Synology 8 Bay DiskStation DS1821+ (Diskless), 8-bay 4gb ddr4 ( ) As a simpler test, I could even just order an 8 or 10 bay ASUSTOR - Asustor Lockerstor 8 AS6508T - 8 Bay NAS, 2.1GHz Quad-Core, 2 M.2 NVMe SSD Slot, 10GbE Port, 2.5GbE Port, 8GB RAM DDR4, Enterprise Network Attached Storage (Diskless) ( ), put my existing disks into it and see what happens. I cannot justify this to validate whether your hardware is faulty. ) This givers me am outlay of $1,500 plus tax. For me to swap out the data/disks in place, I would need to buy 5 drives costing over $300 apiece and up to $500 (e.g. Jack, As I have detailed above, I have the AS6604T filled with 2 x12TB and 2x14TB drives. After several rounds of useful conversation, I was finally told that all my disks were not on their compatibility list and, to move forward, I would need to recreate the problem with disks on that compatibility list. I opened a ticket on on Novemand have been communicating with them ever since. Several of you have commented on difficulty gettig ASUSTOR to respond. Updated summary of my current state - apologies in advance as it has turned in a weighty tome. This seems like a particularly dumb recovery process as, assuming one of the drives might have been impacted, you have a 50/50 chance of corrupting the other vs saving the other. The recovery process merely seems to be to copy every bit from the first drive in the RAID1 pair to the second drive in the RAID1 pair regardless. Problem happens less often as less activity is going on but does not go away.Īnyone know how to diagnose the problem or have any suggestions?Īs one last ditch effort, anyone know how to go from RAID1 to single? The BTRFS implementation on the ASUSZTOR (and perhaps universally) appears to go in synchronization if the device crashes while writing. I have tired re-initializing all drives but the NVMe which holds Volume1 and removing all USB connections (including the expansion unit for a period of time). those on the list have not been reported as problematic, those not on the list have just not been reported as good or bad and I find it hard to believe that drives fdrom major manufacturers are incapable of normal operation. It more seems to be the result of anecdotal experience, e.g. I have tried opening a ticket with ASUSTOR and they have not solved the issue but have suggested that the disks are not on their compatibility list but this list does not seem to be the result of specific testing. Internal drives are all WD shucked drives.Īll drives holding original data are btrfs, backup drives are EXT4.ĭevice is connected to my internal network using Link aggregation It seems to be more likely to happen when multiple tasks are moving large amounts of data to / from the disks.ĪDM 4.0.1.ROG1 is installed on Raid 1 consisting of 2xCrucial P5 500GB 3D NAND NVMe Internal SSD, up to 3400MB/s - CT500P5SSD8.Īdded 4 additional gig of memory shortly after purchase via Crucial RAM 4GB DDR4 2400 MHz CL17 Laptop Memory CT4G4SFS824A. This data movement did no cause the problem. e.g., I just added a new shucked 14tb WD drive in the expansion unit (AS6004U) and backed up one RAID1 pair without issue then added a second drive via USB port and backed up another RAID1 pair. Problem can be recreated (sometimes) by moving large amounts of data from one drive to another but this is not always the case. This happens anywhere from multiple times a day to once a week. On restart, one or more of the RAID1 pairs resynchronizes (which takes almost a day for larger pairs). The control panel is non-responsive so one has to hold the power button and force power off the unit. AS6604T LockerStor freezes and disconnects from network.
