Storage & filesystems

WebGen is a rescue-and-manage surface: boot from USB, read and manipulate common disk/image formats, and reach network storage.

Local filesystems: ext4 (e2fsprogs), XFS, Btrfs, FAT/exFAT (dosfstools, exfatprogs), plus the kernel’s NTFS and UDF.

Encryption: LUKS via cryptsetup (dm-crypt, XTS).

Network storage: NFS (nfs-utils) and SMB/CIFS (cifs-utils); the kernel exports NFS (nfsd).

Enterprise SAN: the kernel carries iSCSI, Fibre Channel, NVMe-over-Fabrics, device-mapper multipath, and the GFS2/OCFS2 cluster and Ceph RBD block clients — modules that stay inert until the matching hardware or target is present.

The userland for the common cases is packaged, but deliberately kept out of the base image so a laptop does not carry a SAN stack it will never use. Install what you need:

wgpkg install lvm2 open-iscsi multipath-tools

That gives you lvm / pvs / vgs / lvs and dmsetup, iscsiadm / iscsid, and multipath / multipathd.

Still absent, so the matching kernel client cannot be used at all: the GFS2/OCFS2 cluster userland (corosync, dlm, gfs2-utils, ocfs2-tools) and Ceph's (ceph-common, rbd). The kernel modules are there; without the tools to join a cluster or map an RBD image, nothing can mount them.
