I'm using multiple 600+ megabyte (0.6tb) filesystems SATA Raid server on my home fileserver using ext3, and I'm not seeing any problems. (I have 3tb of space, but for management reasons I elected to divvy up the space into smaller volumes.) I'm using a 2.6.18-rc2 kernel with the Areca ARC-1160 controller, with Areca firmware version 1.41. (I haven't upgraded to 1.43 yet, even though it just became available a few month or two.) It's been working just fine, and I've had any issues with it.

When you say it's reproducible, has it been reproducible after using mke2fs to reformat the filesystem, perhaps with a manually specified filesystem size? E2fsck should have complained if the filesystem size was larger than the apparent size of the physical volume, but if the Areca firmware somehow screwed up and reported a larger size that what was actually there, then both mke2fs and e2fsck will blindly believe what the BLKGETSIZE64 ioctl returns (they won't use the binary search method of determining the disk size unless the GETBLKSIZE/GETBLKSIZE64 ioctls fail for one reason or another), and if there was some wraparound bug, that would explain what you're seeing. So the only other thing I can suggest is to double check the filesystem size as reported by dumpe2fs or df, and compare it with the raw volume size as reported by the Areca management interface; do the numbers look sane? = Ted _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
