I'm building a backup to disk system and i have strange problem with lvm=20 on top of 2 software raid 5 devices. Each SW Raid-5 has 7x400GB HDDs (=3D2,4TB). On top of these two SW Raid=20 devices I created one big LV with 4,8TB. I use Reiserfs as filesystem. I worked fine while the disk usage was=20 below 1,5TB, above that, the Filesystem was destroyed. I tried the same=20 with ext3 and had the same results. So I't not the Filesystem. I also=20 checked the Softwareraid and the LV for any Problems but i haven't found=20 anything. After reading many Mails/howtos/man-pages I quess that LVM can't handle=20 PV's which are larger than 2TB is this correct? I haven't found anything in the documentation about the maximum PV size. thanks for any help.
