There are messages from syslog: ----------------------------------------------------------------------- Jan 22 23:43:16 localhost EXT3 FS on sdb1, internal journal Jan 22 23:43:16 localhost EXT3-fs: mounted filesystem with ordered data mode. ----------------------------------------------------------------------- Then I copied my data to this new partition. I could access this data from new partition without any problems. Next day: ----------------------------------------------------------------------- Jan 23 10:23:46 localhost VFS: Can't find ext3 filesystem on dev sdb1. ----------------------------------------------------------------------- > It looks like when you moved the data onto the new partition, it got > written somewhere on the disk.

This does > happen when you delete two or more partitions and create one large one. Why it can happen when replacing two partitions with large one? I tried gpart with this output: ----------------------------------------------------------------------- #gpart /dev/sdb Begin scan...

It produces same output. But I created ext3 on whole disk, I'm sure. -- gentoo-user@gentoo.org mailing list
