HI, Thanks for the quick response. I think the situation is different then what you describe since we have abut 10 FS with the same size 2142.1 GB that have no problem.

Hm, I think you just stated the root cause. Did the filesystem work fine until you rebooted it? Did it used to be 8T? And did you use parted to create it? Parted wrongly allows you to make a >2T msdos partition table and pokes it directly into the kernel, but the on-disk format cannot hold the large value. So when you reboot, it's read as something smaller. You might be able to do a trick where you create a new GPT label in place of the old DOS label, with the same start point as the dos label, but with a correct endpoint. I would not repair the fs; if my guess is right, 3/4 of it is now unreachable and fsck will probably do heavy damage. -Eric _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
