I have a Debian 8 VM with:
- 1x virtual root disk
- 1x virtual data disk with a ZFS file system on it.
When I initially created the ZFS file system, I did not manually create partitions, but simply ran this command:
zpool create -f my-pool /dev/sdb
Later, I expanded the virtual disk with the ZFS file system, but my ZFS pool would not recognise the bigger size without me resizing the ZFS partition, but another partition was in the way of type: "Solaris reserved 1", so I deleted it.
All seems to have worked fine, but I am concerned:
- Why did ZFS create a second partition on the disk reported by fdisk -l as type: "Solaris reserved 1"?
- Did I break anything I might not be aware of?
Here is the fdisk -l output PRIOR to deleting partition 9 in order to expand partition 1:
Disk /dev/sdb: 1.7 TiB, 1864015806464 bytes, 3640655872 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Device Start End Sectors Size Type /dev/sdb1 2048 3221207039 3221204992 1.5T Solaris /usr & Apple ZFS /dev/sdb9 3221207040 3221223423 16384 8M Solaris reserved 1
parted just showed it like this:
Model: VMware Virtual disk (scsi) Disk /dev/sdb: 1864GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 1649GB 1649GB zfs zfs-515ff33e31a51432 9 1649GB 1649GB 8389kB
Am I ok, or do I need to be concerned? Any clue what on earth a "Solaris reserved 1" partition type is? Why was it created in the first place?
