At the end of the output, it will print the device size required to restore it. rhbz#503529 --- gfs2/edit/savemeta.c | 35 +++++++++++++++++++++++++++++++---- 1 files changed, 31 insertions(+), 4 deletions(-) diff --git a/gfs2/edit/savemeta.c b/gfs2/edit/savemeta.c index 76f37ab..687dbc2 100644 --- a/gfs2/edit/savemeta.c +++ b/gfs2/edit/savemeta.c @@ -666,10 +666,27 @@ void savemeta(char *out_fn, int saveoption) exit(0); } +/** + * anthropomorphize - make a uint64_t number more human + */ +static const char *anthropomorphize(unsigned long long inhuman_value) +{ + const char *symbols = " KMGTPE"; + int i; + unsigned long long val = inhuman_value; + static char out_val[32]; + + memset(out_val, 0, sizeof(out_val)); + for (i = 0; i < 6 && val > 1024; i++) + val /= 1024; + sprintf(out_val, "%llu%c", val, symbols[i]); + return out_val; +} + int restore_data(int fd, int in_fd, int printblocksonly) { size_t rs; - uint64_t buf64, writes = 0; + uint64_t buf64, writes = 0, highest_valid_block = 0; uint16_t buf16; int first = 1, pos; char buf[256]; @@ -735,9 +752,9 @@ int restore_data(int fd, int in_fd, int printblocksonly) sbd1->sb_header.mh_format == GFS_FORMAT_SB && sbd1->sb_multihost_format == - GFS_FORMAT_MULTI) - ; - else if (check_sb(&sbd.sd_sb)) { + GFS_FORMAT_MULTI) { + gfs1 = TRUE; + } else if (check_sb(&sbd.sd_sb)) { fprintf(stderr,"Error: Invalid superblock data.\n"); return -1; } @@ -750,6 +767,9 @@ int restore_data(int fd, int in_fd, int printblocksonly) "%u bytes in the destination" \ " file system.\n\n", last_fs_block, sbd.bsize); + } else { + printf("This is %s metadata\n", gfs1 ? + "gfs (not gfs2)" : "gfs2"); } first = 0; } @@ -757,6 +777,8 @@ int restore_data(int fd, int in_fd, int printblocksonly) print_gfs2("%d (l=0x%x): ", blks_saved, savedata->siglen); block = savedata->blk; + if (block > highest_valid_block) + highest_valid_block = block; display_block_type(savedata->buf, TRUE); } else { warm_fuzzy_stuff(savedata->blk, FALSE, FALSE); @@ -779,6 +801,11 @@ int restore_data(int fd, int in_fd, int printblocksonly) } if (!printblocksonly) warm_fuzzy_stuff(savedata->blk, TRUE, FALSE); + else + printf("File system size: %lld (0x%llx) blocks, aka %sB\n", + (unsigned long long)highest_valid_block, + (unsigned long long)highest_valid_block, + anthropomorphize(highest_valid_block * sbd.bsize)); return 0; }
