#514 hptrr on 6.x-RELEASE/i386 causes filesystem damage and panic
I'm currently running FreeNAS 0.69 Kwisatz Haderach (revision 4276), and have been seeing errors on the console and in the logs indicating disk errors. The drive is attached using a Highpoint RocketRAID RR1742 (using only for SATA, not using any RAID functions). HPTRR currently autoloads at boot. Errors occur during reads/writes. The hard drive is new and has been tested with diagnostics (full sector by sector read tests etc.) without errors. I think the problem may actually be due to a bug reported with the HPTRR module for the Highpoint RocketRAIDs included in the FreeBSD 6.3+ kernel (see link: http://www.jp.freebsd.org/cgi/query-pr.cgi?pr=kern/120615). I realize it's been reported as a FreeBSD bug, but FreeNAS is probably affected also since it's based on it.
I tried unloading HPTRR (kldunload hptrr) in order to load rr174x-6.1.ko instead, but receive No Such File or Directory error message (I'm not sure how to do this, so I'm probably doing something wrong). When attempting to kldload rr174x-6.1.ko, I receive the error rr174x: no controller detected. I'm guessing this is because hptrr is already loaded for this controller.
Can a fixed version of HPTRR be added to FreeNAS, or possibly remove it or disable it from autoloading to allow loading a different driver? I'm not exactly sure how to disable it to prevent it from autoloading.
Seems there is no patch available for FreeBSD 6.x (http://www.freebsd.org/cgi/query-pr.cgi?pr=120615), so i can't do anything here. But as mentioned in the PR FreeBSD 7 does not have the problem. Maybe you should update to FreeNAS 0.7.
