I 1st observed this while moving some data around on one of my disks.
- 4 disk array (1x parity, 3x data).
I observe this behaviour on the drive with zfs file system.
Running the following command I moved multiple copies of a Windows10.iso file one folder up.
I can see that RAM is filling up:
Unraid GUI only shows read activity on the disk3 and NO writes.
Unitl I get this:
The moved files are lost!
3 out of 5 files were moved and nothing can be found in the target folder.
And Unraid UI is crashing due to lack of free RAM.
Any ideas?
I know that zfs is using RAM to buffer file transfer, but this does not make any sense.
I lost an unknown number of files due to this issue...
Luckily, I just moved between servers and the old one still holds a copy ....
