MFV r354382,r354385: 10601 10757 Pool allocation classes
illumos/illumos-gate@663207adb1669640c01c5ec6949ce78fd806efae https://github.com/illumos/illumos-gate/commit/663207adb1669640c01c5ec6949ce78fd806efae 10601 Pool allocation classes https://www.illumos.org/issues/10601 illumos port of ZoL Pool allocation classes. Includes at least these two commits: 441709695 Pool allocation classes misplacing small file blocks cc99f275a Pool allocation classes 10757 Add -gLp to zpool subcommands for alt vdev names https://www.illumos.org/issues/10757 Port from ZoL of d2f3e292d Add -gLp to zpool subcommands for alt vdev names Note that a subsequent ZoL commit changed -p to -P a77f29f93 Change full path subcommand flag from -p to -P Portions contributed by: Jerry Jelinek <jerry.jelinek@joyent.com> Portions contributed by: HÃ¥kan Johansson <f96hajo@chalmers.se> Portions contributed by: Richard Yao <ryao@gentoo.org> Portions contributed by: Chunwei Chen <david.chen@nutanix.com> Portions contributed by: loli10K <ezomori.nozomu@gmail.com> Author: Don Brady <don.brady@delphix.com> 11541 allocation_classes feature must be enabled to add log device illumos/illumos-gate@c1064fd7ce62fe763a4475e9988ffea3b22137de https://github.com/illumos/illumos-gate/commit/c1064fd7ce62fe763a4475e9988ffea3b22137de https://www.illumos.org/issues/11541 After the allocation_classes feature was integrated, one can no longer add a log device to a pool unless that feature is enabled. There is an explicit check for this, but it is unnecessary in the case of log devices, so we should handle this better instead of forcing the feature to be enabled. Author: Jerry Jelinek <jerry.jelinek@joyent.com> FreeBSD notes. I faithfully added the new -g, -L, -P flags, but only -g does something: vdev GUIDs are displayed instead of device names. -L, resolve symlinks, and -P, display full disk paths, do nothing at the moment. The use of special vdevs is backward compatible for read-only access, so root pools should be bootable, but exercise caution. MFC after: 4 weeks
