Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

I know this is the old thread,but anyway this problem still persists in many distros. I've found sane workaround to it. Using *x-systemd.after=iscsi.service* mount option adds necessary dependency to mount and prevents iscsi to log out before the file system is clearly unmounted. here is the

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

I just want to thank David and Chris for sorting this out. I had exactly the same problem: CentOS 7 system "hanging" on shutdown when iSCSI volume is mounted, but not when unmounted and logged out of iscsi session first; iSCSI session not logging in automatically on startup. As Chris

CentOS7 and systemd ordering when shutting down results in unclean unmount

Setup iSCSI on CentOS7. Mounted a iSCSI disk and am running a small MySQL instance on the disk. The iSCSI disk and MySQL instance all come online fine with booting but when shutting down things seem to get very upset and the drive does not get unmounted cleanly. Does not look like I'm the only

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

I'm not familiar with CentOS. Does you iscsi-utils package have any systemd unit files, i.e. is the version of open-iscsi you are using integrated with systemd? On Tuesday, December 9, 2014 7:28:52 AM UTC-8, awidde...@hotmail.com wrote: Setup iSCSI on CentOS7. Mounted a iSCSI disk and am

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

Yes, it does. These are the two main unit files provided for open-iscsi. The first is to log in/out of all automatic targets on startup/shutdown: [Unit] Description=Login and scanning of iSCSI devices Documentation=man:iscsid(8) man:iscsiadm(8) DefaultDependencies=no Conflicts=shutdown.target

Sorry, I didn't post the fstab entry in my original post when I should have. The _netdev entry is being applied to the disk and it seems like systemd generator is seeing that option properly and creating the mount point correctly (or so I think). Here is the fstab entry: LABEL=/iscsi-disk

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

It seems clear that the I/O error is because iscsi is stopped before the device is unmounted: On Tuesday, December 9, 2014 7:28:52 AM UTC-8, awidde...@hotmail.com wrote: Setup iSCSI on CentOS7. Mounted a iSCSI disk and am running a small MySQL instance on the disk. The iSCSI disk and MySQL

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

Okay, I'm no systemd expert, though I play one at work. :) You might try adding this to your mysql unit file: [Unit] Description=MySQL Server -After=nss-lookup.target network.target remote-fs.target time-sync.target -Wants=nss-lookup.target network.target remote-fs.target time-sync.target

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

Thanks for the feedback and suggestion. I'm fairly certain (haven't actually tried though) that adding iscsi-disk.mount or even iscsi.target to the After= of the MySQL service would probably solve this problem I don't think it's a good solution. Just to start, I don't think the MySQL package

Re: CentOS7 and systemd ordering when shutting down results in unclean unmount

I'm not sure if it is the unit files, iscsi or even systemd itself that is the problem. It all seems very strange to me right now. I certainly will post back if it is an open-iscsi issue. As I said, doesn't really seem like the unit files and their requirements are misconfigured. My hunch is
