TWE driver IOCTL's

[Eduard Martinescu]

Hello,

I looking to extend the smartmontools support
(/usr/ports/sysutils/smartmontools) to include support for drives behind
a TWE device.

I looked at the source for the TWE driver, and it seems to support what
I neednot sure yet, as the linux version use the ATA Passthru
IOCTL.  At any rate, there does not appear to be any twe.h include files
installed into /usr/include anywhere for my program to be able to pick
the correct definitions.  Is this just an oversight? Or did I miss
something?

Thanks,
Ed

Re: Too many uncorrectable read errors with atang

If you are running -CURRENT, you can check the SMART status of the
drives with the port sysutils/smartmontools.  If the drive supports >
ATA-3 commands, you should be able to see if there are errors being
reported by the drive itself.

Experimental port of smartmontools available

[Eduard Martinescu]

 All,
 
 The current CVS version of smartmontools
 http://smartmontools.sourceforge.net now has support for FreeBSD.
 
 A couple of notes:
 
 1) SCSI support is there, but has not been highly tested.  It uses CAM, so
 any version of FreeBSD with CAM should work (hopefully)
 
 2) ATA support requires ATAng, or a fairly recent CURRENT. 
 
 I do plan on eventually creating a /usr/ports/systutil/smartmontools and
 submitting to the appropriate place, but haven't gotten there yet.
 
 Please try it out and send any problem reports to the smartmon-support
 mailing list.
 
 Thanks,
 Ed
