My NC is working fine.
But one day I wanted to play with docker 😅 and wanted to split my NC DB (MySQL) into different ip.
BUT Direct Error...
Error code.
SQLSTATE[HY000][2002] Connection Refused
I would like to know why this is happening, thanks.
In Array , I have a verify disk (Seagate IronWolf Pro) and three Seagate IronWolf disks.
But for some reason the writing speed suddenly drops (the writing process is writing to disk1)
Anyone can explain this? thx
Before I shutdown, I saw all my files on the newdisk (that should mean it's really transferred, right?)
Just after reboot, the data is almost gone (remove the auto-generated docker.img, only about 10 gb left...)
I run "mv -fC olddisk newdisk" and then shut down the machine
I have confirmed that the data has been moved, but I did not expect the data to disappear directly after reboot...
My Array and pool are both in btrfs format
For some reason, I had to transfer the data from the xfs drive to the Array via the "mv" command (can't via unbalance)
But after rebooting, the transferred data is gone, I'm very frustrated now.😥😥
Is there any rescue method? thanks a lot!!
*The target disk (new disk) is in btrfs-encrypt format.
*The new disk should be full normally
