While today it froze again during SATA access (a mac synced it's timemachine backup via SMB), I reviewed again some log files and this time found something interesting: The SATA RAID array is syncing in the background.
The system worked stable for half a year. And then, this happened: Oct 3 00:57:01 hhtpc CRON[8078]: (root) CMD ([ -x /usr/share/mdadm/checkarray ] && [ $(date +%d) -le 7 ] && /usr/share/mdadm/checkarray --cron --all --quiet) Oct 3 00:57:01 hhtpc mdadm[1743]: RebuildStarted event detected on md device /dev/md0 This was exactly the event when the trouble started and the system freezes sometimes during SATA accesses. I now have the "theory" that the freeze occurs if I start the backup from the SATA RAID array to another SATA/PATA drive while the RAID sync is running, or vice vera. I'll check this out ... What happened on 3. oct? I applied some ubuntu updates. I rebooted. -- computer freeze on disc operation with very large files/amounts of blocks https://bugs.launchpad.net/bugs/654163 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
