I just grow a xfs filesystem (44To), and no way to mount it anymore : > XFS: device supports only 4096 byte sectors (not 512) Did you expand an LV made of 512-sector physical devices by adding 4k-sector physical devices? that's probably not something we anticipate or check for.... What sector size(s) are the actual lowest level disks under all the lvm pieces? -Eric > # xfs_check /dev/vg0/tomo-201111 > ERROR: The filesystem has valuable metadata changes in a log which needs to > be replayed.

I cant think it caused this issue... I saw there can be problem with underlying device (an ARECA 1880).
