Hopefully someone can help on this maybe "bug" ? I've read about something like that from Robert Mustacchi ...
Here's the config: Quadmirror ZFS: 2 Discs in DC1 / 2 Discs in DC2 (works perfect for Metro Style Cluster) If we use iSCSI Disc on this config we get the following: (checked in this config and even on the same box) Here's the error: c0t600144F0908AC7035000C5005750CEF7d0 Soft Errors: 0 Hard Errors: 10 Transport Errors: 0 Vendor: SEAGATE Product: ST2000NM0023 Revision: 1.0 Serial No: Z1X0Z1GS Size: 2000.40GB <2000398868480 bytes> Media Error: 0 Device Not Ready: 0 No Device: 10 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c0t600144F0908AC7025000C5005715B7A3d0 Soft Errors: 0 Hard Errors: 10 Transport Errors: 0 Vendor: SEAGATE Product: ST2000NM0023 Revision: 1.0 Serial No: Z1X0KPAX Size: 2000.40GB <2000398868480 bytes> Media Error: 0 Device Not Ready: 0 No Device: 10 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c0t600144F0908AC7015000C5005743530Bd0 Soft Errors: 0 Hard Errors: 10 Transport Errors: 0 Vendor: SEAGATE Product: ST2000NM0023 Revision: 1.0 Serial No: Z1X0WQA0 Size: 2000.40GB <2000398868480 bytes> Media Error: 0 Device Not Ready: 0 No Device: 10 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 c0t600144F0908AC7275000A7203008BE03d0 Soft Errors: 0 Hard Errors: 9 Transport Errors: 0 Vendor: STEC Product: ZeusRAM Revision: 1.0 Serial No: STM000185B19 Size: 8.00GB <7999934464 bytes> Media Error: 4 Device Not Ready: 0 No Device: 5 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 zpool import send an SCSI_RESERVATION Command to the Discs to claim it, this is answered with an SCSI_RESET_TARGET (sic!!!) There's no SCSI_RESET_LUN in the iSCSI Specs - so during Initialize and reading configs of Discs the STMF Target got resetted (each disc in DC1 and DC2) - for some IOPS .... That seems to be a bug - as it couldn't really be a wanted feature :-) What we tried for testing: There are no errors on SAS Discs (physical) zpool import / export works BIOS on each disc is the same The error just occurs on "import and create (not during operation on the metro cluster) " Any idea on this?
