Zvol's clones giving through ctld (100 clients). There is freeze in Windows client on 5-10 seconds, respectively clients NTFS Windows are under zfs zvols. Problem begining when we destroyd old clones and snapshots and maked new snapshots and clones. uname -a FreeBSD bsd 11.2-RELEASE FreeBSD 11.2-RELEASE #0 r335510: Fri Jun 22 04:32:14 UTC 2018 root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 Configuration zpool: atime=off dedup=off sync=disabled compression=lz4 Конфигурация CTLD: portal-group test { discovery-auth-group no-authentication listen 192.168.173.206:3260 } target iqn.orig1 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/orig/original1 ctl-lun 194 }} target iqn.orig2 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/orig/original2 ctl-lun 195 }} target iqn.orig3 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/orig/original3 ctl-lun 196 }} target iqn.orig4 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/orig/original4 ctl-lun 198 }} target iqn.games { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/hdd/orig/games ctl-lun 197 }} target iqn.pc1 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/snap/win1 ctl-lun 1} lun 1 { path /dev/zvol/hdd/snap/win1 ctl-lun 101}} target iqn.pc2 { auth-group no-authentication portal-group test lun 0 { path /dev/zvol/ssd/snap/win2 ctl-lun 2} lun 1 { path /dev/zvol/hdd/snap/win2 ctl-lun 102}} So until iqn.pc100.
