For unknown reasons, I've got around 2TB (assuming 512 bytes per sector) of unreadable sectors:

smartd[5904]: Device: /dev/twa0 [3ware_disk_29], 4294967295 Currently unreadable (pending) sectors smartd[5904]: Device: /dev/twa0 [3ware_disk_29], 4294967295 Offline uncorrectable sectors

The disk is a 750GB ST3750640A with firmware version 3.AAE. The RAID controller has not reported any issues with this disk. There are multiple disks of this model and firmware revision attached. This is the only abnormal one. As smartmontools is reporting this as an issue, upstream monitoring systems are being triggered. Can a way to supress this specific number of bad sectors, or condition (2TB on a 750GB disk) be created?

Nor does disk appear to have an issue:

Hi,

I've attached a patch that allows smartctl to access SATA drives on LSI 3ware 9750 controllers.

I've been using this version on multiple systems (with 3ware 9650, 9750, and on-board SATA and SAS only) for almost a month without any problems.

Please let me know if I need to make changes and re-submit it again, or if there's a different procedure for submitting this patch.

Regards,

Victor

When attempting to access the my 3ware SAS9750-4i4e RAID controller I get the error below (regardless if I choose the controllers device id or a drive through the controller. I'm currently using SATA disks only (I hear there are issues accessing SAS disks through the 3ware drivers).

Command: smartctl -a /dev/tws0 -d 3ware,0 Output: /dev/tws0: 3ware controller type unknown, use /dev/tweX or /dev/twaX devices

Command: smartctl -a /dev/da0 -d 3ware,0 Output: /dev/da1: 3ware controller type unknown, use /dev/tweX or /dev/twaX devices

I can provide access to the hardware if needed.
