Hello, I have 3 partitions with btrfs(/, /home and /data). All of them have following mount options
noatime,space_cache,inode_cache,compress=lzo,defaults Whenever there is a unclean shutdown(which happens a lot in my case), the next reboot, system comes up relatively at the same speed but as systemd is starting up daemons, the disk is continuously ( and unusally long) grinding. This causes random delays with various daemons such as postgresql failing to start, kdm timing out of xorg servers etc and I have to reboot after the dust settles to bring back the system to the normal. At one time, even keyboad/mouse were not responding as some debus service timed out.. I think it is rebuilding the space cache because I saw similar long disk activity when I activated it first. How can I confirm that it is the space cache rebuild thats taking time? if space cache rebuild is the reason, is there any way to improve it? I am running archlinux/systemd/kde setup with two 7200 RPM seagate sata disks(no RAID, one 80 GB for / and /home, other 500GB for data). The kernel is 3.9.8 x86_64. Thanks. -- Regards Shridhar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
