Hi All, I've noted some posts regarding resyncing issues with 2.6.6 so I thought I'd forward this one on just in case. Unfortunately I'm not able to gather much hard info, so apologies if I'm too vague. The problems started with a sector error on device (1) of a ATA raid 1 array (extfs3), apparently looping and stating something about md and illegal sector on /dev/hdc2. Unfortunately I wasn't there to witness first hand and the error was not written down. (Just reboot the machine and see if that fixes it!!!) Anyway an md resync ensured following the reboot, when 100% was reached the system immediately switched to read-only, no syslog entries... The console was spewing out errors "md: error in start_transaction: Read Only file system". Had to forcibly reboot after 10 minutes waiting for reboot to occur. After an fsck and another reboot all is UU OK. I've been running raid on the machine for a couple of years, I've had two drive failures in that time (raid worked perfectly without interuption) and not had an issue til now following a relatively recent kernel upgrade from 2.4.20 5 weeks ago to 2.6.7 and 2 weeks ago 2.6.8. Using ... md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27 on Debian unstable Cheers, Lewis - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
