So earlier this month my second parity drive fell out of sync. I tried three times to resync it, it failed every time. I tried Pre-clean and it also failed. So that 14TB has probably bit the dust.

About a week later, drive 6, an 8TB, also fell out of sync. When I tried to resync it, it got to about 11%, and the rate dropped to several BYTES per second. I cancelled it, rebooted the server, and tried again. This time it got to 4.3%, and has been stuck there for quite some time. It expects to be done in 18 years, which I guess is better than the 1,000 years last time. It is currently working at 9-15KB/sec.

So I am sitting here with NO wiggle room, one more issue and I'm toast, I assume that because I was rebuilding Disk 6 it is worthless at this point for recovery.

Any advice on why my server is slowing down during rebuild (I'm running Minecraft on Crafty-4 and it has not had any issues)

You are using a controller with an STA port multiplier, causing issues for multiple drives, example:

Jul 7 16:35:38 Kaokulk kernel: ata12.03: hard resetting link

Jul 7 16:35:38 Kaokulk kernel: ata12.03: SATA link up 6.0 Gbps (SStatus 133 SControl 330)

Jul 7 16:35:44 Kaokulk kernel: ata12.04: link is slow to respond, please be patient (ready=0)

Jul 7 16:35:48 Kaokulk kernel: ata12.04: softreset failed (device not ready)

Jul 7 16:35:51 Kaokulk kernel: ata12.15: qc timeout after 3000 msecs (cmd 0xe4)

Jul 7 16:35:51 Kaokulk kernel: ata12.04: failed to read SCR 0 (Emask=0x4)

Jul 7 16:35:51 Kaokulk kernel: ata12.04: reset failed, giving up

Jul 7 16:35:51 Kaokulk kernel: ata12.04: failed to recover link after 3 tries, disabling

Recommends replacing that with one from the recommended list, then post new diags after array start
