I have a zpool that has been plagued due to physical disk failures. The zpool consists of two raidz2s. There are a few disks that have been removed from the zpool due to failure, and otherwise, the data on failing disks has been copied to new media and the few (<10 per disk) blocks that were unreadable and filled with zeros. I have reached a configuration that, while short of the full number of disks, has no failing disks involved. I have been able to import the zpool and access all data without errors. The problem is that in the process of resilvering, the system panicked. Now I have a pool I can''t import, not even with the following in /etc/system: set aok=1 set zfs:zfs_recover=1 And yes, I am remembering to delete /etc/zfs/zpool.cache. And I tried importing read-only. And I tried a live disc. I know the data is intact (there''s enough parity) and every disk is functioning properly. But some kind of subtle corruption is preventing it from importing and resilvering at this point. If I return some of the failing media to the zpool, I am able to import it. However, the failing media results in either glacially slow access times and/or the disk is faulted at some point. This basically doesn''t help me. Is there any way to overcome this crashing problem? My only other option is to copy the failing disks to new media, block level, filling any unreadable blocks with zeros. But this is time consuming and frankly, I am running out of disk media. And the whole point of a zpool is so that it manages the storage so I don''t have to do stupid things like this. Ideas anybody? -Galen
