Experiencing this same issue with iSCSI and systemd-239 for RH8/Rocky8
and RH9/Rocky9 system-252. Nothing was done on my end to create this
issue. In other words, no custom mount/unit files or services, just
your typical ISO install and rpm updates.
An ordering cycle occurs, when "_netdev" is specified within /etc/fstab
for systemd. This happens with systemd-239-14 and systemd-239-18 using
iSCSI based file systems. Seems others are experiencing this as well
(see link below). I can also confirm this happens with systemd-252
(RH9/Rocky9)l. Especially if "_netdev" is used with either "/var" or
"/usr" iSCSI based devices/file systems. The system may not boot, may
not mount file systems, may not start services/unit files, and the
system becomes slow during system boot.
Does anyone know of a fix/patch and root cause for this?
