Whenever I try to start the lvm service (openrc) if fails with the following output. It should be noted though, that the lvm volumes are all there and lvm is working without any observable issues. # /etc/init.d/lvm start * Starting the Logical Volume Manager ... Found volume group "vgdata" using metadata type lvm2 Found volume group "vgsystem" using metadata type lvm2 Command failed with status code 5. 12 logical volume(s) in volume group "vgdata" now active 7 logical volume(s) in volume group "vgsystem" now active * Failed to start the Logical Volume Manager [ !! ] * ERROR: lvm failed to start It seems that the erroneous return code is issued by the vgscan command with --mknode parameter. When this parameter is removed, the issue is not present. # vgscan --config 'global { locking_dir = "/run/lock/lvm" }' --mknodes Found volume group "vgdata" using metadata type lvm2 Found volume group "vgsystem" using metadata type lvm2 Command failed with status code 5. A log with -vvvv is attached to the bug report. However, I cannot find any message about a failed node creation or a similar issue. The only thing special to that system seems to be that it runs a software raid 5, containing a luks container which then contains the physical volume of the volume group vgdata. However, the lvm command already fails at boot time. when the luks container is still closed. Thus, this contradicts this point. I found an old similar report here https://gitlab.alpinelinux.org/alpine/aports/-/issues/3543 but the issue is refereed to as fixed by this commit

I have the same symptoms here, temporary solution is removing the --mknodes option from the startup script. The system runs on md-raid1 PVs without initramfs. Interestingly, there is no startup script for lvmetad installed.

Interesting that you are also using mdraid. Since mdraid and lvm are both using the device mapper, my hypothesis is that mdraid is creating some device mapper nodes prior to lvm and that this causes lvm to fail when it tries to create the nodes itself. Maybe return code 5 is not an issue at all and should be simply ignored by the init script? However, i cannot find a documentation regarding the return code and what is exactly means or if it is also used for more severe situation. (lvmetad was deprecated and is gone since version 2.03. Thus, missing lvmetad is expected and should not be of concern)
I do not use LVM2 to manage the RAID setup, this is left to the boot time kernel auto-raid feature and the mdadm. But my LVM uses RAID devices /dev/md* as PVs. So I'm not longer sure, if the bug title relates to my situation, but the symptoms are the very same.
I have confused md and dm devices... My setup is also using md devices onthe bottom of the stack. More precisely mdraid -> luks -> PV.
I have the same issue with the '--mknodes' option. I removed it from my init.d/lvm script and all is good. I think the issue is that mknodes should not be used when 'udev' is enabled since udev takes care of creating all device mapper nodes. A secondary issue to failing to start 'lvm' is that other services like 'lvmpolld' won't work without it. Maybe there ought to be a check for udev in the init script, or in the ebuild to prevent this issue?
crowsnest [16:46:36] ~ # vgscan --mknodes; echo $? Found volume group "lvm" using metadata type lvm2 Command failed with status code 5. 5 crowsnest [16:46:48] ~ # vgscan; echo $? Found volume group "lvm" using metadata type lvm2 0 crowsnest [16:46:53] ~ # vgscan --mknodes; echo $? Found volume group "lvm" using metadata type lvm2 Command failed with status code 5. 5 So can confirm that --mknodes in combination with thin-volumes cause this. Will have to check if this also happens when udevd is NOT running, but from what I can tell based on simply reading our initrd (and knowing it will block and wait for init rd "recovery shell" on command failures I don't think it does). I would thus suggest to *not* use --mknodes if (and only if) udevd is running.
I don't think any of the Gentoo maintainers are using lvm in this configuration (OpenRC/thin-volumes). I suspect most of us are using systemd now. Patches welcome.
Nope, I do use thin volumes, and no systemd. I can't reproduce your problem. # ps faux |grep -i -e ude[v] -e system[d] root 6654 0.0 0.0 23660 6004 ?

So it's something specific to the thin volumes that mysqld (and seemingly others in the past) use or do. Do we care to figure out exactly what? I would have guessed thin snap related, but on the new nodes (11 of them) where I'm seeing this error we don't have snapshots (yet). Previously we only saw this on a handful of nodes so I didn't bother to try and figure it out. The output from lvs -o +lv_all is rather hard to read as a matter of fact, so I'm not sure how you'd like to proceed if we do want to figure it out. Might be udev/lvm version related and that it was fixed somewhere along the line and since I'm using stable and not ~ for this package ... So lvm2 2.03.21 compared to 2.03.22? Either way, I've pushed a PR for -r4 in the interim, not sure why hppa, ppc, ia64, alpha and m68k keywords were dropped for -r3 - so PR has to be well reviewed.
I've had cases where the device nodes did NOT get created without --mknodes and I couldn't boot, so I'm wary about merging a change to not create them. Yes, that output is hard to read, but there's also the json. sudo lvs -o +lv_all --reportformat json # This shows the 3x sparse-thin LVs I have. sudo lvs -o +lv_all --reportformat json |jq '.report|.[]|.lv|.[]|select(.lv_layout|match("thin"))|select(.lv_layout|match("sparse"))' I'm on sys-fs/lvm2-2.03.22-r2 here right now.
(In reply to Robin Johnson from comment #13) > I've had cases where the device nodes did NOT get created without --mknodes > and I couldn't boot, so I'm wary about merging a change to not create them. Do you perhaps have information on that? Was it if udevd was not running? In our initrd we still have this: /sbin/lvm vgscan --mknodes --quiet At this point udevd is NOT running, and --mknodes is required. Since this is what we term a "managed command" (ie, it has to succeed) at this point we know that this works correctly. The follow-up /sbin/lvm vgchange --sysinit -a ay --quiet --ignoremonitoring however is set to permit failure (causes a delay of 30 seconds, but this gives an opportunity in the case of this being a real problem for a sysadmin to interfere), since that does still fail with exit code 5 on thin LVs. > Yes, that output is hard to read, but there's also the json. > sudo lvs -o +lv_all --reportformat json Gets marginally easier, but as per https://bugs.gentoo.org/889559 we merely need to create a thin pool for this issue to exhibit itself. Even after passing that via jq. > # This shows the 3x sparse-thin LVs I have. > sudo lvs -o +lv_all --reportformat json |jq > '.report|.[]|.lv|.[]|select(.lv_layout|match("thin"))|select(. > lv_layout|match("sparse"))' I really need to learn jq query syntax :). > I'm on sys-fs/lvm2-2.03.22-r2 here right now. The relevant PR still issues vgchange with --mknodes if udevd is NOT running. It does this by checking if /run/udev/control is a socket (if it is, we don't pass --mknodes, if it's not a socket, we pass --mknodes).
I debugged this on my Debian system which exhibits the same error. The issue is that in one particular bit of code, it skips the thin pool LV, but fails to override the return code from the default error value. This issue has been fixed in 2.03.22 already: https://github.com/lvmteam/lvm2/commit/e3cc3e55c8e75f20997f321bfac766859337bef6 This explains why Robin can't reproduce the issue, as 2.03.22 versions in Gentoo went stable relatively recently.
*** Bug 889559 has been marked as a duplicate of this bug. ***
Based on further testing I concur that this has been fixed upstream in version 2.03.22 of the lvm2 package (link in directly preceding comment). I'm closing this as fixed since same version is also now marked as stable.
