Hi,
I am running a small FreeBSD DIY NAS. When I upload large amounts of data (for example, photo galleries with several hundreds of pictures including RAW files), the copy process often hangs. Sometimes, it continues after a while and sometimes I have to reboot the FreeBSD box. Copy processes are started on Windows10 clients using Samba or Debian 10 using NFSv4.
Data is stored on a zpool consisting of three identical 4TB WD Red harddisks configured as raidz1.
ZFS dataset compression and deduplication are turned off.
Memory shouldn't be an issue.
However, I am not sure if the CPU could be a limiting factor and hinder FreeBSD to write data quickly on disk.
Can you suggest any parameters for tuning the system?
Goal would be to have stable copy processes even if the write rate slows down a bit.
Thanks and best regards
