On Fedora 30 the paritition sizes turn out to be too small again:
+ mkdir -p /sysroot
+ mount /dev/dracut/root /sysroot
+ cp -a -t /sysroot /source/bin /source/dev /source/etc /source/lib /source/lib64 /source/proc /source/root /source/sbin /source/sys /source/tmp /source/usr /source/var
cp: error writing '/sysroot/usr/lib64/libkrb5.so.3.3': No space left on device
cp: error writing '/sysroot/usr/lib64/libkrb5support.so.0.1': No space left on device
It turns out that there has been quite some size increase in some libraries,
notably glibc, though not all -- some even shrunk, ruling out a toolchain
problem. Here's are files over 1M we install on Fedora 30:
f29 f30
2.7M => 6.4M /usr/lib64/{libc-2.28.so => libc-2.29.so}
3.1M => 6.0M /usr/lib64/libcrypto.so.1.1.1c
2.0M => 3.5M /usr/lib64/{libm-2.28.so => libm-2.29.so}
2.9M => 2.8M /usr/lib/systemd/{libsystemd-shared-239.so => libsystemd-shared-241.so}
1.7M => 2.5M /usr/lib64/libunistring.so.2.1.0
2.3M => 2.4M /usr/lib64/bind9-export/libdns-export.so.1105.0.0
1.2M => 2.1M /usr/bin/bash
1.1M => 1.4M /usr/lib64/libkrb5.so.3.3
1.2M => 1.4M /usr/lib64/libgcrypt.so.20.2.4
612K => 1.1M /usr/lib64/libssl.so.1.1.1c
This increases the image sizes to accomodate for this. There's probably
little else we can do.
According to Cathy Zhou <Cathy.Zhou@Oracle.COM>:
"iscsistart is not designed to be working together with iscsid. When an
interface gets the dhcp offer successfully, the iscsiroot script is run
which starts the iscsistart service to establish the iSCSI session. With
the existence of iscsid, the iscsistart service's attempt to setup its
own mgmt ipc fails. Instead, the request to login to the iscsi target
is handled by the mgmt ipc of iscsid. After iscsistart finishes its
login attempt, it eventually sends a stop_event_loop request to stop
the mgmt process. As the result, it terminates iscsid."
So, iscsid is kicked out again.
Additionally iscsistart-flocked is used to make sure iscsistart is not
run in parallel.
