I do use resize2fs. The process is to grow the lun. Then you have to delete and add in a new partition because the old partition will be smaller than the size of the new lun. Then one the partition fills up the lun, you run resize2fs to grow the file system. I am using a 64bit OS. After more testing, it seems to have something to do with 1 TB. I can grow a lun (and file system) from 700GB to 900GB or from 1.1TB to 1.4TB. I just cannot grow from 900GB to 1.4TB. I have posted a question on this to the open-iscsi group to see if they have ever run into this before. Thanks for the information on the 2TB limit with MBR partition tables. I will look into the GPT option. cheers, ski After more testing -- "When we try to pick out anything by itself, we find it connected to the entire universe" John Muir Chris "Ski" Kacoroski, [email protected], 206-501-9803 or ski98033 on most IM services _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
