Salve a tutti,
ho il sistema in firma e vorrei sapere se è possibile convertire la partizione root (che attualmente usa reiser) in modo da usare ext3 senza dover reinstallare.
Ho trovato questa procedura:
OpenSuSE 10.2 was just released and one of the big announcements was the switch from reiserFS to ext3 as the default filesystem format. The reason given was that development work on reiserFS-3 has come to a halt and SuSE was the only distribution championing it.
This gave me a twinge of regret as I had dwelled on this decision when formatting my /home filesystem during SuSE 10.0 installation and ended up choosing the loser. I decided to convert before upgrading my OS. After rereading a comparison review of the various Linux filesystem formats, I chose ext3.
I have been using star to do backups and was planning to use it to backup/restore onto a newly created ext3 partition. Then (in the star man page) I discovered instructions for synchronizing two filesystems.
My second 30Gb OS partition is free so I will create an ext3 clone of /home there. I will use this /home to be sure the transfer is correct before erasing the data from my current reiserFS /home partition.
Here is the command sequence:
1. umount /export/sda9 # (currently empty reiserFS partition)
2. mkfs.ext3 -nv /dev/sda9 # look before leaping
3. mkfs.ext3 -v /dev/sda9 # reformat as ext3
4. vim /etc/fstab # convert sda9 mount from reiserfs to ext3
5. mount /export/sda9
6. star -c -xdev -sparse -acl -link-dirs level=0 -C /export/sda8 . | \
star -xpU -restore -C /export/sda9
7. diff -r /export/sda{8,9}/home # just to be sure
8. vim /etc/fstab # edit /home “bind” mount to ext3
9. reboot
I’m now running on the ext3 /home partition and everything seems fine. After I’m convinced I’ve introduced no latent problems, I’ll do the same sequence in the other direction, ending up with /home back on the 80GB partition as an ext3 filesystem.

Che ne pensate?
E' fattibile e (relativamente sicura)?
Grazie,

PS per quanto riguarda linux ho solo due partizioni: root con all'interno la home e swap
