Hi,

I have some errors about my disk

vnode_pager_getpages: I/O read error
vm_fault: pager read error, pid 7318 (locate)
ad4: FAILURE - READ_DMA status=51<READY,DSC,ERROR> 
error=40<UNCORRECTABLE> LBA=33973759
g_vfs_done():ad4s1d[READ(offset=15037333504, length=36864)]error = 5
vnode_pager_getpages: I/O read error
vm_fault: pager read error, pid 7318 (locate)
pid 7318 (locate), uid 0: exited on signal 11

g_vfs_done():ad4s1d[READ(offset=15037333504, length=36864)]error = 5
vnode_pager_getpages: I/O read error

vnode_pager_getpages: I/O read error

I would like to transfer data to other disk but with minimum downtime. I 
was wondering if this was possible with gmirror. For example I create
gmirror on this disk and than add another so data would be synced.

Does this make any sense or is there better idea.

regards

Uros
