Running zfs tests
Setup VM with:CPU - 4Memory - 8GBHard disk - 100GB (for software installation) SATAThree additional hard drives - 8GB (for zfs test) SATA or NVME
names of other pools
Do not create pools with names that can be used in the tests, i.e. testpool*. otherwise the tests work incorrectly.
Have to use DEBUG build, where we have debug macro
Create user:
useradd -m -d /var/ztest -g staff -s /bin/bash ztest
# add password for remote ssh
passwd ztestAdd user to sudo:
echo "ztest ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/ztestInstall packages for zfs tests:
