Consider upgrading the Linux kernel. > mdadm: Cannot set bitmap file for /dev/md0: Cannot allocate memory How big is your array? The default bitmap-chunk-size when the bitmap is in a file is 4K, this makes a very large bitmap on a large array. Try a larger bitmap-chunk size e.g. mdadm -G --bitmap-chunk=256 --bitmap=/raid.bm /dev/md0 > [root@st-0001 root]# free > total used free shared buffers cached > Mem: 2073152 75036 1998116 0 4 29304 > -/+ buffers/cache: 45728 2027424 > Swap: 0 0 0 > [root@st-0001 root]# mdadm -X /dev/md0 This usage is only appropriate for arrays with internal bitmaps (I should get mdadm to check that..). > > And now what? :-) Either create an 'internal' bitmap, or choose a --bitmap-chunk size that is larger. Thanks for the report.
