I wrote and asked for help about ten days ago with no response. Please give me some guidance if you can.

I have been running unRAID successfully for the past three years without any problems. Over time I have added to the system with no problems.

Current system: MB- ASUS P5LDN VM, 1mb memory, Celeron 2.2gHZ dual core CPU, pair of Promise SATA300 TX4 controllers, Corsair TX650 power supply, running unRAID Server Pro 4.5.6

Connected to MB SATA: Parity- 1.5TB Seagate, D1&D2-Hitachi 1TB, D3- WD 1TB

Connected to Promise PCI 1: D4-SG 1.5TB, D5- WD 0.75TB, D6- WDEARS 1.5TB (jumpered)

Connected to Promise PCI 2: D7-SG 0.5TB, D8- SG 1.5TB, Cache- SG 0.5TB

There was less than 1TB free out of 8.75TB.

I decided a couple of weeks ago to upsize my parity drive to 2TB and eventually add larger drives to the system, so ten days ago I checked the parity, shut the system down cleanly, removed the old parity drive and replaced it with a new SG 2TB in the parity slot. The system recognized the new drive and I assigned it as parity in slot 1 (same as old parity) and restarted he system. The parity sync began. Shortly after, I lost contact with the server via desktop (MacMini) and cannot access via browser or smb. Also at the same time the console connected to the server froze - no keys work, the keyboard remains plugged in. I have attached a screenshot of the server console.

I don't know what rate the parity sync is running. Matter of fact, I don't know if it is even still running.

Is there any way to see the progress and tell if it's still running. I can hear individual discs spinning every once in a while and they all appear to be connected in running. I just need to know if I should let it continue for God knows how long or cut my losses, do a hard shutdown (I have no access to the machine other than the power button), reload my old parity drive and reboot.

Please let me know if there are any solutions.

PS- I can use terminal on the mac and it will connect to the ip address. I just don't know what to do once it does.

Thanks in advance.

Given the length of time it's been running, I'd do a hard shutdown => you can try a momentary press of the power button and see if that invokes a "clean" shutdown (wait 5-10 minutes to give it a chance);  but I doubt that will work.    If not, just hold the power button until the system turns off.

 

When you restart the system, you're going to be in a "running at risk" situation (i.e. you don't have valid parity), so any drive failures are going to = data loss until you get a good parity sync completed.

 

SO, since that's the case, I'd recommend taking the opportunity to simply upgrade to v5.  You may even want to use a 4TB parity drive in that case, so you can add larger drives going forward (just use the 2TB drive you have as a new data drive).

   

Thanks-

I went ahead and did a hard shut down. Removed the new parity drive and replaced it with my existing. Upgraded flash to 4.7, rebooted and parity was valid. Powered down and upgraded flash to 5.04. Restarted and set up all disks as directed in read me files. Everything works exactly as it should, parity is valid.

I'm in the process of building new box with a ASUS A8N-SLI, and pci express controller cards. With the software upgrade, I will go ahead and order a 4TB drive for parity and do a new parity sync with the faster SATA connections.

Thanks again for your help.

Excellent -- glad all's running well; and now that you're on v5, you can get your parity drive bumped up to 4TB and can then increase your space much easier in the future.
