# LC_ALL=C ./xfs_repair -vv -m 1 /dev/vg_sys/lv_storage1
Phase 1 - find and verify superblock...
        - max_mem = 1024, icount = 97495744, imem = 380842, dblock = 
1884752896, dmem = 920289
Required memory for repair is greater that the maximum specified
with the -m option. Please increase it to at least 1319.
