Hi Roland,
The probem seems to be that SYS/var is mounted on /var after initializing unionfs.
#mount tmpfs on /run type tmpfs (rw,relatime) tmpfs on /union/rw type tmpfs (rw,relatime,size=1048576k) devtmpfs on /dev type devtmpfs (rw,relatime,size=32794936k,nr_inodes=8198734,mode=755) unionfs on / type fuse.unionfs (rw,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other) /dev/ram0 on /union/image type squashfs (ro,relatime) /dev/ram0 on /union/rw/union/image type squashfs (ro,relatime) SYS/var on /var type zfs (rw,relatime,xattr,noacl)
I think to problem lay in a miss configuration of unionfs when loading the following configuration file:
cat /etc/qlustar/disk-config # ZFS config for 2 disks (/dev/sda - /dev/sdb) as stripe (RAID 0): # Zpool name: SYS # 16GB zvol for swap (not activated) # Filesystems: /var (max 2GB) + /scratch - both compressed
[BASE] ZPOOLS = SYS ZFS = var, scratch ARC_LIMIT = 1024 #ZVOLS = swap
[SYS] vdevs = V-SYS
[V-SYS] devs = /dev/sd[ab] type =
[swap] zpool = SYS size = 16G
[var] zpool = SYS quota = 2G reservation = 2G compress = lz4
[scratch] zpool = SYS compress = lz4
So it seems that the unionfs /var is overwritten by SYS/var.
Best,
Kwinten
