I'd switched back to .30 for the arm system because of this. (And on the s390 box I looked for sda instead of dasdb; duh!) Here are the values for arm: $ cat /sys/block/sda/sda6/alignment_offset 0 $ cat /sys/block/sda/queue/physical_block_size 512 $ cat /sys/block/sda/queue/logical_block_size 512 And here's the lot for the s390 emulator: # grep . /sys/block/dasdb/dasdb*/alignment_offset /sys/block/dasdb/dasdb1/alignment_offset:0 /sys/block/dasdb/dasdb2/alignment_offset:0 # grep . /sys/block/dasdb/queue/physical_block_size 4096 # grep . /sys/block/dasdb/queue/logical_block_size 4096 # pvs -o +pe_start PV VG Fmt Attr PSize PFree 1st PE /dev/dasdb1 mordor lvm2 a- 388.00M 0 192.00K /dev/dasdb2 mordor lvm2 a- 388.00M 0 192.00K # dmsetup ls mordor-home (254, 0) # dmsetup table mordor-home: 0 794624 linear 94:5 384 mordor-home: 794624 794624 linear 94:6 384 # fdasd -p /dev/dasdb reading volume label ..: VOL1 reading vtoc ..........: ok Disk /dev/dasdb: cylinders ............: 1113 tracks per cylinder ..: 15 blocks per track .....: 12 bytes per block ......: 4096 volume label .........: VOL1 volume serial ........: 0X0121 max partitions .......: 3 ------------------------------- tracks ------------------------------- Device start end length Id System /dev/dasdb1 2 8346 8345 1 Linux native /dev/dasdb2 8347 16694 8348 2 Linux native -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
