This seems to go back a long way in history [1], but I think it has always been broken.

The xfs_repair "-t" option shouldn't be used alone. An interval must follow the -t option, or xfs_repair will report errors. And only modify reporting interval is useless, if we don't enable ag_stride. Signed-off-by: Zorro Lang <zlang@redhat.com> --- Hi, I don't know why we must need the -t option for xfs_repair, I can't find any description to explain it. But I can find an explanation about why we use "-t" for _xfs_check. # xfs_check runs out of memory on large files, so even providing the test # option (-t) to avoid indexing the free space trees doesn't make it pass on # large filesystems. Avoid it. The -t option for xfs_repair is totally different with it for xfs_check, maybe -m option is more useful if we think about the memory size. And the -t option need to work with -o ag_stride together. I'd like to remove the "-t" option directly, due to I really don't know why we need it, or how to give it a proper number. If the original author knows why we need it, and can give me some suggestions, please help. Thanks, Zorro common/xfs | 1 - 1 file changed, 1 deletion(-)
