:What does this kernel messages mean?
:Aug 11 19:27:05 kernel: Warning: vfsync_bp skipping dirty buffer
:Aug 11 19:57:40 kernel: Warning: vfsync_bp skipping dirty buffer
:Aug 11 20:58:52 kernel: Warning: vfsync_bp skipping dirty buffer
You can ignore these warnings. They typically occur under heavy
I/O loads. The buffer will still be synced (eventually).
:My machine is a eeepc900 with a ssd disk, can it be that the ssd is not
:that supported yet?
:I'm using UFS as filesystem, beacuse i read somewhere that Matt wrote we
:should't use HammerFS with filesystems under 40GB, this drive is on 16GB.
:And i wonder what this means too:
:ad2: FAILURE - SET_MULTI status=51<READY,DSC,ERROR> error=4<ABORTED>
:ad2: 15391MB <ASUS-PHISON SSD TST2.04P> at ata1-master UDMA66
UFS is probably the best choice for a 16G drive.
The SET_MULTI failures can probably be ignored. My guess is that the
SSD simply does not support the command.... not surprising if it is a
modern SATA drive.
