vdo_initiali...ume_geometry(9)
β¨ vdo_initialize_volume_geometry(9) β¨
okay so real talk, bestie β this is a page straight out of the Kernel API Manual, and the header up top literally got truncated to vdo_initiali...ume_geometry(9) because man pages are dramatic and love to cut off a girl mid-sentence π. The actual function is vdo_initialize_volume_geometry, section 9, and it lives over in ./drivers/md/dm-vdo. Yes, the section is part of the name, no we're not gonna fight about it π
.
πΈ NAME πΈ
vdo_initialize_volume_geometry β bestie, it initializes the volume geometry so that it can be written out. That's the whole vibe. It sets the thing up so the thing can be yeeted onto disk. π
π¦ SYNOPSIS π¦
int vdo_initialize_volume_geometry (nonce_t nonce , uuid_t *uuid , const
struct index_config *index_config , struct volume_geometry *geometry );
literally just look at it. four arguments. one int coming back at you. she's serving β¨
π ARGUMENTS π
nonceβ this is anonce_t, and it's the nonce you use to identify the vdo. iconic little identifier, no cap π«Άuuidβ this one's auuid_t *, the uuid you use to identify the vdo. yes, both a nonce and a uuid, she contains multitudes πindex_configβ aconst struct index_config *, and it's the config used for structure initialization. the blueprint, the mood board, the whole plan πgeometryβ astruct volume_geometry *, and it's the volume geometry you're about to initialize. main character energy fr fr π
π RETURN π
Returns VDO_SUCCESS or an error code. that's it, that's the deal β slay if it works, check the error code if it doesn't π
lowkey important: it hands back VDO_SUCCESS or an error code, so please actually look at what comes back instead of just assuming everything's fine, bestie π
π₯ SEE ALSO π₯
okay so the SEE ALSO section on this one is long, like she did not come to play. The kernel file in question is ./drivers/md/dm-vdo/encodings.c, and here's the whole squad, every single one, no skips:

and that's the page, bestie π β brought to you by the fine folks at ./drivers/md/dm-vdo, stamped October 2026, and filed under the Kernel API Manual. go initialize something iconic πβ¨
