Re: [Linux-cluster] gfs2_grow does not work



Appreciate for your reply!


[root wplccdlvm445 ~]# uname -r
2.6.18-164.el5

[root wplccdlvm445 ~]# rpm -qa |grep gfs
gfs2-utils-0.1.44-1.el5
gfs-utils-0.1.17-1.el5

I am using the packages shipped by Redhat, no any customization. Does
it mean gfs2_grow does not work at all in 5.4 release(I wish I am
wrong)?

I did not find any patch for x86 32 bit CPU,  it does have x86_64.

A recent kernel patch from https://bugzilla.redhat.com/show_bug.cgi?id=457798 changed that to take the mountpoint as the first arg instead. There was a corresponding userland patch to gfs2-utils in https://bugzilla.redhat.com/show_bug.cgi?id=459630#c3 that fixed this mismatch.
