Figure out what's broken in your hardware?

This is not a postgresql issue, it is a bad hardware / driver issue. PostgreSQL cannot cause a SCSI reset etc on its own, it requires something be broken in the OS / hardware for that to happen. > I have no real evidence of bad disks...iostat -E reports: No, but this iostat output is evidence of a bad SAN driver / SAN or something around there. > > # iostat -E > sd2 Soft Errors: 1 Hard Errors: 4 Transport Errors: 0 > Vendor: Pillar Product: Axiom 300 Revision: 0000 Serial No: > Size: 2.20GB <2200567296 bytes> > Media Error: 0 Device Not Ready: 0 No Device: 4 Recoverable: 0 > Illegal Request: 1 Predictive Failure Analysis: 0 > sd3 Soft Errors: 1 Hard Errors: 32 Transport Errors: 0 > Vendor: Pillar Product: Axiom 300 Revision: 0000 Serial No: > Size: 53.95GB <53948448256 bytes> > Media Error: 0 Device Not Ready: 0 No Device: 32 Recoverable: 0 > Illegal Request: 1 Predictive Failure Analysis: 0 > sd7 Soft Errors: 1 Hard Errors: 40 Transport Errors: 8 > Vendor: Pillar Product: Axiom 300 Revision: 0000 Serial No: > Size: 53.95GB <53948448256 bytes> > Media Error: 0 Device Not Ready: 1 No Device: 33 Recoverable: 0 > Illegal Request: 1 Predictive Failure Analysis: 0 > sd8 Soft Errors: 1 Hard Errors: 34 Transport Errors: 0 > Vendor: Pillar Product: Axiom 300 Revision: 0000 Serial No: > Size: 107.62GB <107622432256 bytes> > Media Error: 0 Device Not Ready: 0 No Device: 34 Recoverable: 0 > Illegal Request: 1 Predictive Failure Analysis: 0 > sd9 Soft Errors: 1 Hard Errors: 32 Transport Errors: 2 > Vendor: Pillar Product: Axiom 300 Revision: 0000 Serial No: > Size: 215.80GB <215796153856 bytes> > Media Error: 0 Device Not Ready: 1 No Device: 29 Recoverable: 0 > Illegal Request: 1 Predictive Failure Analysis: 0 -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
