Hi -
By making a dump-md of a several TB device I expected to get a
relatively large file. I realize that it is actually the opposite: the
dump does only contain a dozen lines, like following.
# DRBD meta data dump
# 2013-03-11 18:38:21 +0100 [1363023501]
# nfs-2> drbdmeta 0 v08 /dev/vg1/storage internal dump-md
#
version "v08";
# md_size_sect 139512
# md_offset 2339289165824
# al_offset 2339289133056
# bm_offset 2339217739776
uuid {
0x7117E0379FF23460; 0x0000000000000000; 0x6273B7EE32734046;
0x6272B7EE32734047;
flags 0x00000091;
}
# al-extents 3389;
la-size-sect 4568784648;
bm-byte-per-bit 4096;
device-uuid 0x64B2B985FCFD7314;
la-peer-max-bio-size 131072;
# bm-bytes 71387264;
bm {
# at 0kB
8923456 times 0x0000000000000000;
}
# bits-set 0;
Is this normal or do I missed something?
PS: the dump-md drbdadm command requested that I first drbdadm apply-al
before being able to dump de meta-data.
Thanks and best regards,
