Errors on SSD

[Sven Gaerner <sgaerner@xxxxxxx>]

Hi,

I updated my system to the latest release version. The uname says:
3.0-RELEASE DragonFly v3.0.3.1.g2c987-RELEASE.

I guess it is not related to the kernel version, but I'm getting these
messages on the console. I didn't see them before.

ahci0.2: TFES slot 21 ci_saved = 00200000
ahci0.2: disk_rw: error
ahci0.2: TFES slot 22 ci_saved = 00400000
ahci0.2: disk_rw: error
ahci0.2: TFES slot 22 ci_saved = 00400000
ahci0.2: disk_rw: error
ahci0.2: TFES slot 3 ci_saved = 00000008
ahci0.2: disk_rw: error
ahci0.2: TFES slot 5 ci_saved = 00000020
ahci0.2: disk_rw: error
ahci0.2: TFES slot 7 ci_saved = 00000080
ahci0.2: disk_rw: error

That device is an SSD.

ahci0.2: Caps 42006<HPCP,MPSS,POD,SUD>
ahci0.2: PMPROBE(2) No Port Multiplier was found.

ahci0.2: Found DISK "OCZ-VERTEX2 1.29" serial="OCZ-CU25VMZ6117F3NFM"

I'm using that disk for the root file system, including /tmp, /usr, /var
and for running swapcache. All other stuff are on magnetic hard
disks. The usual hammer configuration has been modified to reduce
writing to the disk and follows Matt's suggestions [1].

Thanks to hammer a backup of the PFSs is not a problem. But I would like
to know if someone else has seen those messages and can provide some
details about possible errors. Do I have to expect a failing disk soon?

I also have set kern.cam.da.2.trim_enabled to 1.

Thanks.

Sven
