baoooooo

Absolutely right. I didn't pay attention to the link speed info before JorgeB pointed out this 😅

Really appreciate. Yes, it is exactly the reason. The built-in NICs are proven good after my test. The malfunctioning part is either the network cable or the RJ 45 port. I moved my NAS to another room and connected to a different port , now everything is fine. Guess that I would spend some time diagnostic which part of the cable/port goes wrong. Thanks!

No.. it's a NAS essentially. It comes with 2 *2.5Gb Ethernet port. Thanks for your input - I might need to have a test with it's original software to verify its builtin NICs(although it's a new HW just purchsed. ).

I have set the "Enable auto start" to "Yes" in Settings -> "Disk Settings". Tried multiple reboots (1) with or without this options = yes/no and (2) with array status staying at "started"/"stopped" prior to reboot (all combination) but no luck. Looking at the systemlog and the only 2 suspicious log messages seem to be Sep 24 13:37:16 Tower emhttpd: shcmd (6): /sbin/modprobe md-mod super=/boot/config/super.dat Sep 24 13:37:16 Tower kernel: md: unRAID driver 2.9.27 installed >>>(1)>>>Sep 24 13:37:16 Tower emhttpd: error: get_limetech_time, 286: Connection timed out (110): -2 (7) >>>(1)>>>Sep 24 13:37:16 Tower emhttpd: Unregistered Trial - no connection (ENOCONN) Sep 24 13:37:16 Tower emhttpd: Device inventory: Sep 24 13:37:16 Tower emhttpd: ST1000DM003-1SB102_Z9ACL8WA (sdb) 512 1953525168 Sep 24 13:37:16 Tower emhttpd: USB_SanDisk_3.2Gen1_0101185f2af97aa23644da3d94d11df5c02b3e55a9576b7ef29537f3de3 (sda) 512 30081024 Sep 24 13:37:16 Tower kernel: mdcmd (1): import 0 >>>(2)>>>Sep 24 13:37:16 Tower kernel: md: import_slot: 0 empty Sep 24 13:37:16 Tower kernel: mdcmd (2): import 1 sdb 64 976762552 0 ST1000DM003-1SB102_Z9ACL8WA Sep 24 13:37:16 Tower kernel: md: import disk1: (sdb) ST1000DM003-1SB102_Z9ACL8WA size: 976762552 Sep 24 13:37:16 Tower kernel: mdcmd (3): import 2 Sep 24 13:37:16 Tower kernel: mdcmd (4): import 3 Sep 24 13:37:16 Tower kernel: mdcmd (5): import 4 Sep 24 13:37:16 Tower kernel: mdcmd (6): import 5 Sep 24 13:37:16 Tower kernel: mdcmd (7): import 6 Sep 24 13:37:16 Tower kernel: mdcmd (8): import 7 Sep 24 13:37:16 Tower kernel: mdcmd (9): import 8 Sep 24 13:37:16 Tower kernel: mdcmd (10): import 9 Sep 24 13:37:16 Tower kernel: mdcmd (11): import 10 Sep 24 13:37:16 Tower kernel: mdcmd (12): import 11 Sep 24 13:37:16 Tower kernel: mdcmd (13): import 12 Sep 24 13:37:16 Tower kernel: mdcmd (14): import 13 Sep 24 13:37:16 Tower kernel: mdcmd (15): import 14 Sep 24 13:37:16 Tower kernel: mdcmd (16): import 15 Sep 24 13:37:16 Tower kernel: mdcmd (17): import 16 Sep 24 13:37:16 Tower kernel: mdcmd (18): import 17 Sep 24 13:37:16 Tower kernel: mdcmd (19): import 18 Sep 24 13:37:16 Tower kernel: mdcmd (20): import 19 Sep 24 13:37:16 Tower kernel: mdcmd (21): import 20 Sep 24 13:37:16 Tower kernel: mdcmd (22): import 21 Sep 24 13:37:16 Tower kernel: mdcmd (23): import 22 Sep 24 13:37:16 Tower kernel: mdcmd (24): import 23 Sep 24 13:37:16 Tower kernel: mdcmd (25): import 24 Sep 24 13:37:16 Tower kernel: mdcmd (26): import 25 Sep 24 13:37:16 Tower kernel: mdcmd (27): import 26 Sep 24 13:37:16 Tower kernel: mdcmd (28): import 27 Sep 24 13:37:16 Tower kernel: mdcmd (29): import 28 Sep 24 13:37:16 Tower kernel: mdcmd (30): import 29 >>>(2)>>>Sep 24 13:37:16 Tower kernel: md: import_slot: 29 empty However I am not sure if one of them are the root cause or actually no of them are. Some clue that I can think of 1. I am still on a trail license which may have some limitation. However this seems not true because I could not find any documentation on the website regarding this. 2. The Sandisk flash drive was reported it comes without a GUID. I managed to install manually following an official guide. I am wondering if the "malfunctioning" flash drive is causing the trial license not binded correctly? 3. The HW that I am running Unraid is a QNAP 462 NAS (yeah.. I know it sounds ridiculous because it is shipped with a charged SW. I just like the small form of factor and it can sit near my desk) but I doubt it's the least possible cause. Again, I am not sure regarding this. I am looking for any suggestions/hints/answers to help me out. Thanks a lot. tower-diagnostics-20240925-2027.zip
