Hello,
Sorry that I made several posts frequently, but I need help with this soft raid 10.
I replaced two sata cables due to bad cables on the two previous WD 3TB Red a few weeks ago.
Then I created a raid10 fresh using ext4. It working fine a while. But now it keep resync too often after I shutdown the server using rtcwake in crontab.
The log said raid isn't clean, therefore it not shutdown, but resyncing... I've tried both kernels, but no luck.
It finished resynced this morning, but then it's resyncing again after the server woke up this afternoon.
Not only that, but my fdisk said there are no valid partition table for my drives.
I'm in the process replacing the two hard drives that have ATA error count from WD sent me.
HDDs serial numbers have been removed for security purpose.
Hope you guys can help me.
Thanks in advance.
