But we only have a remapper for ext3. > ---- I wondered about that, but the blktrace package doesn't containg any utility for remapping blocks. The blktrace-0.99.3-12 package included in OSuse-10.3, I only see utilities "blkparse, blktrace, btrace, blkrawverify, btt, and verify_blktrace". Was it left out by accident? ---or--- If the remapping is in a separate package, then shouldn't the blktrace package "just" do the block tracing, regardless of file type (i.e. in typical unix fashion, it does its part, and another util (a block-re-arranger) does its part...? Having blktrace do it's thing no matter what filesystem follows might encourage or enable someone to write re-arrangers for other filesystems...(?) After all, xfs already has one block-rearranger program (for what little it is needed) in "xfs_fsr". Does ext3 have something similar now? Was the ext3 block re-arranging tool supposed to be in the blktrace package? thanks, linda
