#! /bin/bash # # storage-fixup - Tejun Heo <teheo@xxxxxxx> # # Script to issue fix up commands for weird disks. This is primarily # to adjust ATA APM setting. Some laptop BIOSen set this value too # aggressively causing frequent head unloads which can kill the drive # quickly. This script should be called during boot and resume. It # examines rules from /etc/stroage-fixup.conf and executes matching # commands. # # In stroage-fixup.conf, empty lines and lines starting w/ # are # ignored. Each line starts with rule, dmi, ata or act. # # rule RULENAME # Starts a rule. $RULENAME can't contain whitespaces. # # dmi KEY PATTERN # Checks whether DMI value for KEY matches PATTERN. If not, the # rule is skipped. # # ata KEY PATTERN # Checks whether ATA value for KEY matches PATTERN. If not, the # rule is skipped. KEY can be one of model, rev and serial. # # act ACTION # Executes ACTION on matched devices. ACTION can contain $DEV # which will be substituted with device file of matching device. # # sact ACTION # Silent version of "act".
