[Parted-maintainers] Bug#291234: parted: No Implementation: This ext2 filesystem has a rather strange layout! Parted No Implementation: This ext2 filesystem has a rather strange layout!

[Joel Soete]

Package: parted
Version: 1.6.11-9
Severity: normal

Hello all,

I am running a debian  unstable' (today updated) with a developement kern=
el
2.6.11-rc1-pa3 on hppa box (b2000).
This system own 2 Disk: one boot disk of 9gb and a 'data' disk of 36Gb.

the boot disk sda has the following slicing schema (cfdisk):
Disk /dev/sda: 9100 MB, 9100044288 bytes
64 heads, 32 sectors/track, 8678 cylinders
Units =3D cylinders of 2048 * 512 =3D 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          61       62448   f0  Linux/PA-RISC boo=
t
/dev/sda2              62         306      250880   82  Linux swap / Sola=
ris
/dev/sda3             307         367       62464   83  Linux
/dev/sda4             368        8557     8386560    5  Extended
/dev/sda5             368        1953     1624048   83  Linux
/dev/sda6            1954        2197      249840   83  Linux
/dev/sda7            2198        2319      124912   83  Linux
/dev/sda8            2320        2441      124912   83  Linux
/dev/sda9            2442        4394     1999856   83  Linux
/dev/sda10           4395        6347     1999856   83  Linux
/dev/sda11           6348        8300     1999856   83  Linux
/dev/sda12           8301        8557      263152   83  Linux

And the second disk:
Disk /dev/sdb: 36.4 GB, 36420075520 bytes
64 heads, 32 sectors/track, 34732 cylinders
Units =3D cylinders of 2048 * 512 =3D 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       34732    35565552   83  Linux

As I don't need any more to have the full disk for a data slice on this d=
isk,
I would like to use parted to re-partition as:
/dev/sdb1               1          61       62448   f0  Linux/PA-RISC boo=
t
/dev/sdb2              62         306      250880   82  Linux swap / Sola=
ris
/dev/sdb3             307         367       62464   83  Linux
/dev/sdb4             368        8557     8386560    5  Extended
/dev/sdb5             368        1953     1624048   83  Linux
/dev/sdb6            1954        2197      249840   83  Linux
/dev/sdb7            2198        2319      124912   83  Linux
/dev/sdb8            2320        2441      124912   83  Linux
/dev/sdb9            2442        4394     1999856   83  Linux
/dev/sdb10           4395        6347     1999856   83  Linux
/dev/sdb11           6348        8300     1999856   83  Linux
/dev/sdb12           8301       34732    35565552   83  Linux

(for mirroring with raid1)

(in summary:
parted
resize 1 0.016 26432.000 (i.e. 34732 - 8300)
move 1 0.016 8300.000

then create sdb[1..11] )

but when I asked 'parted' to check the disk slice 1:
# ./parted/parted /dev/sdb
[...]
Using /dev/sdb
(parted) p                                                              

Disk geometry for /dev/sdb: 0.000-34732.890 megabytes
Disk label type: msdos
Minor    Start       End     Type      Filesystem  Flags
1          0.016  34732.000  primary   ext3
(parted) check 1                                                        

No Implementation: This ext2 filesystem has a rather strange layout!  Par=
ted
can't resize this (yet).

So am I not very confident to go ahead ;-)

As sudgested on gnu site I grab the last 1.6.21 release which I build
# ../configure --prefix=3D/usr --sbindir=3D/sbin --mandir=3D\${prefix}/sh=
are/man
--infodir=3D\${prefix}/share/info --enable-mtrace --disable-shared  --bui=
ld=3Dhppa-linux
--host=3Dhppa-linux
(as debian debug pkg would do?)

but the pb is the same:
# ./parted/parted /dev/sdb

OTC with the other disk no pb:
