buzzingwires a46001adb9 Allow zhack label repair to restore detached devices. ... This commit expands on the zhack label repair command in d04b5c9 by adding the -u option to undetach a device by regenerating uberblocks, in addition to the existing functionality of fixing checksums, now represented by -c. Previous behavior is retained in the case of no options. The changes are heavily inspired by Jeff Bonwick's labelfix utility, as archived at: https://gist.github.com/jjwhitney/baaa63144da89726e482 Additionally, it is now capable of properly determining the size of block devices and other media, as well as handling sizes which are not divisible by 2^18. This should make it viable for use on physical devices and partitions, in addition to files. These changes should make it possible to import zpools that have had their uberblocks erased, such as in the case of pools rendered inaccessible by erroneous detach commands.
