Thread: How to mount ext3 partition with 16k blocksize?

hi,

have disk contains lvm2-volume has been created readynas, , want access data mounting disk manually hooking workstation.

seems readynas has created ext3 partition blocksize of 16k, gives me following error when try mount it:

code:

ext3-fs: bad blocksize 16384

pvscan gives:

code:

  pv /dev/sdb5   vg c   lvm2 [463,53 gb / 0    free]    total: 1 [463,53 gb] / in use: 1 [463,53 gb] / in no vg: 0 [0   ]

lvscan gives:

code:

active            '/dev/c/c' [463,53 gb] inherit

tune2fs -l on logical volume (/dev/c/c) gives:

code:
