Hi,

I added additional storage to my domU using xm block-attach and tap:aio. Then increased my root device (using vgextend, lvextend and resizefs) which is / or /dev/mapper/VolGroup00-LogVol00. Everything worked fine util I did "xm save domid test1.img"

This stopped my domU. And now when I run: xm create domU -c , I am seeing

But I can run my domU using: xm restore test1.img (ignoring some errors like: EXT3-fs error (device dm-0): ext3_lookup: unlinked inode 726639 in dir #717378
)

So what might have gone bad here?

Thanks !
Paras.
