From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20040914 Firefox/0.10 Description of problem: I had a couple Redhat guys at Linuxworld assure me that RHEL4 would support growing ext3 filesystems online ;) If I execute something like: lvextend -L +16M /dev/vgroot/lv_tmp ext2online /dev/vgroot/lv_tmp I get: ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: ext2_ioctl: Inappropriate ioctl for device ext2online: unable to resize /dev/mapper/vgroot-lv_tmp The man page for ext2online says CONFIG_EXT2_RESIZE needs to be enabled in the kernel configuration. It does not show up in /boot/config-2.6.8-1.528.2.10. Version-Release number of selected component (if applicable): e2fsprogs-1.35-9.5 / kernel-2.6.8-1.528.2.10 How reproducible: Always Steps to Reproduce: lvextend -L +16M /dev/vgroot/lv_tmp ext2online /dev/vgroot/lv_tmp Actual Results: ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: ext2_ioctl: Inappropriate ioctl for device ext2online: unable to resize /dev/mapper/vgroot-lv_tmp Expected Results: Filesystem should be 16MB larger. Additional info:
The kernel portion of online resize did not make it into B1, as we found a problem with the patch just before freeze. It should be enabled in current rawhide kernels, though, and is planned to be fully supported in RHEL4.
