lsm_volume_unmask(3)

💖 lsm_volume_unmask 💖

okay bestie, welcome to the Libstoragemgmt C API Manual ✨ this one's called lsm_volume_unmask and it's the girl who takes the access away. yes, we're doing the revoking one. she said "you can't sit with us" but in storage terms 🎀

---

🌸 NAME 🌸

lsm_volume_unmask — revokes access to a volume for the specified group

like. she un-invites the group from the volume. the mask is OFF. the party is OVER. 💅

---

✨ SYNOPSIS ✨

int lsm_volume_unmask (lsm_connect *conn, lsm_access_group
*access_group, lsm_volume *volume, lsm_flag flags);

it hands you back an int, because of course it does, it's a C API function and they love returning ints 😭

---

🦋 ARGUMENTS 🦋

• conn — a valid connection. like, an actual live one. if it's NULL we're gonna have a bad time.
• access_group — pointer of lsm_access_group. this is the group losing their VIP pass 🎟️
• volume — pointer of lsm_volume. this is the volume that's about to become exclusive 💀
• flags — reserved for future use, must be LSM_CLIENT_FLAG_RSVD. like, that's not a suggestion bestie, that's the rule 🔥

💜 VERSION 💜

1.0

---

🌈 DESCRIPTION 🌈

Revokes access to a volume for the specified group.

that's the whole thing. she's a one-job icon. group had access, now group does not have access, and that is genuinely the entire plot 🫶

---

👑 CAPABILITY 👑

LSM_CAP_VOLUME_UNMASK

this is the capability check you look for, iykyk ⭐

---

🎀 RETURN 🎀

Error code as enumerated by lsm_error_number. so like, here's the whole menu:

• LSM_ERR_OK
  • On success. slay ✨
• LSM_ERR_INVALID_ARGUMENT
  • When any argument is NULL or not a valid lsm_connect pointer or invalid flags or invalid lsm_access_group pointer or invalid lsm_volume.
• LSM_ERR_NOT_FOUND_ACCESS_GROUP
  • When access group not found. she's not in the system, bestie, nowhere 💀
• LSM_ERR_NOT_FOUND_VOLUME
  • When volume not found.
• LSM_ERR_NO_STATE_CHANGE
  • When specified volume is not masked to specified access group. like girl there's nothing to revoke, the volume was never masked to them in the first place 🙈
• LSM_ERR_NO_SUPPORT
  • Not supported. the system said "no ❤️"

fr fr check your return codes. every single one of them. no skipping, no assuming it worked, that's how you end up debugging at 3am 😭

and that's the whole page, bestie!! 🧚 from the Libstoragemgmt C API Manual, this little gem dropped in February 2026, and the source line at the bottom is just lsm_volume_unmask and lsm_volume_unmask(3) looking all cute together. go forth and unmask responsibly 💖🌸✨
