I opened bug #498664 in order to crosswrite the fix from RHEL4 that does statfs_fast in a completely different way (bug #488318). That will fix this gfs_grow issue. So I'm closing this bug as a duplicate, as I did for the RHEL4 equivalent bug #484760. *** This bug has been marked as a duplicate of bug 498664 *** |
Description of problem: When statfs_fast is set on a GFS mount point, the system does not notice when the file system size has changed with gfs_grow. Version-Release number of selected component (if applicable): kernel-2.6.18-128.el5 kmod-gfs-0.1.31-3.el5 gfs-utils-0.1.18-1.el5 How reproducible: Every time Steps to Reproduce: 1. mkfs, mount a GFS file system 2. gfs_tool settune /mnt/foo statfs_fast 1 3. df /mnt/foo 4. increase the size of the file system (lvresize) 5. gfs_grow /mnt/foo 6. df /mnt/foo, compare with step 3 Actual results: [root@dash-02 ~]# lvcreate -n one -L 5G growfs Logical volume "one" created [root@dash-02 ~]# mkfs -t gfs -p lock_dlm -t dash:one -j 3 /dev/growfs/one This will destroy any data on /dev/growfs/one. It appears to contain a gfs filesystem. Are you sure you want to proceed?
