Package: zfs-dkms Version: 0.6.5.7-1 Severity: grave --- Please enter the report below this line. ---
See ZoL bug report. https://github.com/zfsonlinux/zfs/issues/4809 aka Illumos 6513 Short summary: Pools with hole_birth feature enabled are susceptible to irreversible damage interfering with, in particular, proper zfs send/receive behavior. The bug fix is in 0.6.5.8, but does not repair damage already inflicted to the pool. >From the ZoL bugreport, user pcd1193182: > The fix for illumos 6513 will solve this problem, but not retroactively. > In other words, any pools that already have this state will not be fixed; > on such pools, the hole BPs already have their birth times set to zero, > and zfs has no way of telling which ones are bugged and which are right. > Any new pools, created after the fix has been applied, will work.
