pursute Posted November 2, 2018 Share Posted November 2, 2018 (edited) Hi Guys, Thanks in advance for any help. I've been seeing a few CRC errors recently so decided to replace my SAS/SATA cables. I shut the box down cleanly, replaced both cables from the SAS card to the drives and then booted up. The system failed on startup as if it had a dirty shutdown and did not boot. I've had this happen a few times before and been able to recover by rebuilding the USB. To do this I copied all files off the USB to a backup directory, formatted the USB, extracted the install files to it from my previously downloaded zip (unRAIDServer-6.6.2-x86_64.zip) and then overwrote the config directory with the one I copied from the USB. The server now boots successfully, but it doesn't start the array. The disk configuration it presents is the configuration from before I recently performed a disk upgrade. During the recent upgrade I replaced a failed drive, replaced the parity drive with a larger disk and moved the old parity drive in to the array as a data drive. The array had been up and healthy for maybe 3-4 weeks on this new drive configuration. I have not attempted to start the array or move any drives yet. Can I just put all the drives back where they belong and start the array? morgan-diagnostics-20181102-2024.zip Edited November 2, 2018 by pursute Quote Link to comment

If the array was healthy (no disabled drives) and you know the correct assignments you can do a new config, keep current assignments, assign missing disks and check "parity is already valid" before starting the array.

pursute Posted November 2, 2018 Author Share Posted November 2, 2018 That worked thanks. A bit of a bum clenching moment when I hit that start button, but it cam back fine. Thanks for your help. Quote Link to comment
trurl Posted November 2, 2018 Share Posted November 2, 2018 You somehow managed to restore an old configuration. FYI your disk assignments are in config/super.dat. I don't know, maybe the new assignments never got written due the problem with the flash. Quote Link to comment
