:[...] : :> But to be absolutely safe, I would follow Bruce's original suggestion :> and increase BKVASIZE to 64K, for your particular system. :> :> :After doing this and testing our backup script, the machine panicked two :hours later (about half-way through the backup) with :"initiate_write_inodeblock_ufs2: already started" (in :ufs/ffs/ffs_softdep.c)... I guess, block sizes above 16Kb are just buggy :and newfs(8) should be honest about it... : : -mi Well, it's possible that UFS has bugs related to large block sizes. People have gotten bitten on and off over the years but usually it works ok if you leave the 8:1 blocksize:fragsize ratio intact. e.g. if you have a 64KB block size then you should use a 8K frag size. If you have a 32KB block size then you should use a 4K frag size. I think the buffer cache itself is is likely not the source of this particular bug. -Matt Matthew Dillon <dillon_at_backplane.com>Received on Tue Oct 12 2004 - 16:18:18 UTC
