(Although the controllers are set and identified as ATA, because of option ROM clash on that system, which I should eventually get down to fixing...) I have two ZFS pools : - 15 disks on a LSI controller - 2 SSDs on the aformentioned Intel AHCI controller Ever since upgrading to 10.1-RELEASE, eventually, I will get a warning in dmesg on either of the two SSDs : ata0: already running! ata1: already running! Source code for ATA indicates that it is just reprocessing the same query= , and gstat indicates that operations are stuck in the I/O queue without ever being purged. Once it comes to that, the only way to (temporarily) recover is to reboot= =2E Cheers, --=20 Stephane LAPIE, EPITA SRS, Promo 2005 "Even when they have digital readouts, I can't understand them." --MegaTokyo --4ddGswSdwOtJkXiebcJUQTWE9VQVkCBVp Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iF4EAREIAAYFAlSCrI8ACgkQDJ4OK7D3FWT6UwEAgQihwGc5n1wc4mWlX2udDquN IR8qb0LjTR7+t/d8CkQA+wa1sOWh1MQlG+K0D8jppY84C4JS7myeb+IB6Urvz4lX =2tKv -----END PGP SIGNATURE----- --4ddGswSdwOtJkXiebcJUQTWE9VQVkCBVp--
