Fixing error reporting—again
Fixing error reporting—again
After a session at last year's Linux Storage, Filesystem, and Memory Management Summit (LSFMM), Jeff Layton was able to make some improvements to block-layer error handling. Those changes, which added a new errseq_t type to hold an error number and sequence number, seemed to help and were well received—except by the PostgreSQL developers. So Layton led a session at the 2018 LSFMM to discuss ways to improve things further; it would be followed later in the week with a session by one of the PostgreSQL developers to look at the specifics of the problem from their perspective.
