iscsi扩容扫描不同于传统的扫描
传统:
echo "- - -" > /sys/class/scsi_host/host1/scan
应使用iscsi的专用扫描命令
iscsiadm -m session -R
其他参考命令:
# lsblk
# lsscsi -ds
[7:0:0:0] disk TrueNAS iSCSI Disk 360 /dev/sdc [8:32] 42.9GB
[7:0:0:1] disk TrueNAS iSCSI Disk 360 /dev/sdd [8:48] 107GB
7是通道, :0与:1是LUN
使用parted 命令调整sdc1盘的空间
# parted /dev/sdc
GNU Parted 3.3

使用btrfs专用命令扩容至最大
# btrfs filesystem resize max /mnt/disks/TrueNAS_iSCSI_Disk01
Resize device id 1 (/dev/sdc1) from 40.00GiB to max
重新查空间确认是否成功
# df -h
