Please > revise and resend, these blocks could be allocated for the reiser4 storage tree or user data. now they are backup super blocks. if run fsck --build-fs, it recovers the backup data in these blocks currently, so the previousely stored tree data will be lost. > and don't make disk format changes in the future > without discussing them with the rest of the team first. Perhaps you > should start that discussion of this disk format change now.... it was discussed many times already, and I mentioned about it in dev list many times also, e.g. the last email about it was 'format change in the backup layout' from 28/07/04. Btw, You agreed with this backup layout scheem in the 'Reiser4 on-disk format' discussion more then a month ago. -- Thanks, Vitaly Fertman
