9403 assertion failed in arc_buf_destroy() when concurrently reading block with checksum error This assertion (VERIFY) failure was reported when reading a block. Turns out the problem is that if we get an i/o error (ECKSUM in this case), and there are multiple concurrent ARC reads of the same block (from different clones), then the ARC will put multiple buf's on the same ANON hdr, which isn't supposed to happen, and then causes a panic when we try to arc_buf_destroy() the buf. illumos/illumos-gate@fa98e487a9 Reviewed by: George Wilson <george.wilson@delphix.com> Reviewed by: Paul Dagnelie <pcd@delphix.com> Reviewed by: Pavel Zakharov <pavel.zakharov@delphix.com> Approved by: Matt Ahrens <mahrens@delphix.com> Author: Matthew Ahrens <mahrens@delphix.com> |
