Linux 3.0 boots fine. This is not hardware or storage error: only Linux 3.1 cause this. Did some one saw this? What the reason can be behind this? (I'm not sure but this looks like announcing wrong size of block device, so ext3 failing to change it journal).I'm getting this error: Try using the barriers=0 mount option $ grep xvda2 /etc/fstab /dev/xvda2 / ext4 noatime,nodiratime,errors=remount-ro,barrier=0 0 1 Thank tou very much! It works!Early lack of barrier disabling cause only warrning, now it cause I/O error. Anyway, this option "barrier=0" solve the problem. Thank you! _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
