GMIRROR - SYNCHRONIZING 100% stuck

Puma

Hello,

We have a pfsense with 2 disks configured in raid 1 with GEOM Mirrors.

One disk was bad, we had replaced with a new disk. The sync is stuck at 100 % :

gmirror status
                Name    Status  Components
mirror/pfSenseMirror  DEGRADED  ada0 (ACTIVE)
                                ada1 (SYNCHRONIZING, 100%)

I see that the first disk with smart, we have errors when the firewall has rebooted to replace the second disk failed.

SMART Error Log Version: 1
ATA Error Count: 5
        CR = Command Register [HEX]
        FR = Features Register [HEX]
        SC = Sector Count Register [HEX]
        SN = Sector Number Register [HEX]

        CH = Cylinder High Register [HEX]
        DH = Device/Head Register [HEX]
        DC = Device Command Register [HEX]
        ER = Error register [HEX]
        ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 5 occurred at disk power-on lifetime: 20844 hours (868 days + 12 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  40 51 00 00 8c a1 40  Error: UNC at LBA = 0x00a18c00 = 10587136

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name

...

So, we will reinstall pfsense soon but we aren't on site.

Is there a way to unlock this situation please ?

Thanks.

Looks to me like that second disk (ada1) has failed. There probably won't be any way around that without physically replacing the drive.
