Hello!
I've tried to mount an ext2 filesystem image (ca. 1GB) stored on a WIN computer via the loop device under 2.4.22:
(Initially the file scratch2.img is filled with 0s.)
#smbmount //win02/scratch /pro -o username=sambadisk,workgroup=MYDOMAIN #losetup /dev/loop0 /pro/scratch2.img #mke2fs /dev/loop0 #mount /dev/loop0 /scratch -t ext2
#cp -r linux-2.4.22 /scratch cp: cannot create directory `/scratch/linux-2.4.22/drivers/video/sis': Input/output error cp: cannot create directory `/scratch/linux-2.4.22/drivers/video/aty': Input/output error
etc.
#dmesg
EXT2-fs error (device loop(7,0)): read_inode_bitmap: Cannot read inode bitmap - block_group = 4, inode_bitmap = 131073 EXT2-fs error (device loop(7,0)): read_block_bitmap: Cannot read block bitmap - block_group = 4, block_bitmap = 131072
With 'mount /dev/loop0 /scratch -t ext2 -o sync':
#mkdir somedir mkdir: cannot create directory `somedir': Input/output error
#dmesg IO error syncing ext2 inode [loop(7,0):0001e6cf] IO error syncing ext2 inode [loop(7,0):0001e6cf]
I've found a similar problem in the kernel archives with the topic 'Loop devices under NTFS' (Aug 27-28 2002) There was mentioned a patch for 2.5.31 to fix this problem. Hasn't been it applied to stable versions since then? Is there a patch for current versions?
