X-RAID2 is like RAID-5.
I would remove that disk. It's clearly failing and only going to cause problems.
There is a possibility you could have a problem e.g. from another failing disk. RAID isn't a replacement for backing up your data. See Preventing Catastrophic Data Loss
After your volume is redundant again, I would enable disk scrubbing monthly and the Online Filesystem Consistency Check weekly. These are good as they can help problems be detected before they become serious.
