For the last few weeks (maybe months), my main desktop computer does fsck on all (but one) partitions on every reboot. The message displayed translate to "Superblock last write time is in the future (by less than a day, probably due to th hardware clock being incorrectly set)" My setup regarding this is standard and hasn't changed for years : i use ntpd and my hardware clock is set to UTC All my partitions are ext4, i have /dev/sda1 (ssd, i dont think it matters) mounted as root and /dev/sdb{1,2,3,4} mounted on other stuff. On boot, /dev/sda1 is reported 'clean', and every other partition has the problem. The boot time usually very fast (ssd!) now takes ages, and i'm worried about the state of those partitions. Each time the fsck reports no problem. The system is a typical ~amd64 often updated. Reproducible: Always Steps to Reproduce: 1. Turn off computer on evening 2. Bring it on next morning 3.
Is your CMOS battery alive? Please go to the BIOS/EFI prior to the boot and check that hardware time there is correct. If it is reset, please replace your battery. ntp can't fix your time before on-boot fsck by design. Anyway please post your emerge --info.
I don't think a dead CMOS battery would set the time in future. Especially with such precision as "less than a day", could it ? emerge --info : Portage 2.2.18 (python 2.7.9-final-0, default/linux/amd64/13.0/desktop/kde, gcc-4.8.4, glibc-2.20-r2, 3.19.3 x86_64)

I was mentionning ntp to give details on the setup. I've been using it for 20 or more years probably. I did not install it hoping to fix the bug.
(In reply to Thomas Capricelli from comment #3) > I was mentionning ntp to give details on the setup. You are misunderstanding error message. "Superblock last write time is in the future" means that at the moment of file system mount attempt superblock is updated later than current system time. This is perfectly valid in case when CMOS drops your time to manufacturer default value which is less than real time. So your system end up booting "in the past" and thus correct superblock write time becomes "in future" for that system. I had exactly the same problem a while ago. Just replace your battery. To check for this problem, turn off your system for at least 24 hours and go straight to BIOS afterwards.
I (respectfully) disagree. I think I understand the message well. I insisted, and i keep insisting on the fact that the messages also says "less than a day". So a reset to the CMOS default date (1970/1/1) is not the problem heree
(In reply to Andrew Savchenko from comment #4) > I had exactly the same problem a while ago. Just replace your battery. To > check for this problem, turn off your system for at least 24 hours and go > straight to BIOS afterwards. I understand very well. But you might consider that my problem is not the same as the one you had. I've just checked and all my (non-default) cmos settings are still there.
Are you booting using openrc or systemd? What does /etc/conf.d/hwclock contain? What does /etc/adjtime contain (if anything)?
I'm using openrc (emerge --info doesn't report such a useful information !?). /etc/conf.d/hwclock contains clock="UTC" clock_args="" (everything else commented). berlioz ~ # cat /etc/adjtime -13.368038 1254180250 0.000000 1254180250 UTC
If that matters "ntptrace localhost" reports : localhost: stratum 4, offset -0.000418, synch distance 0.108768
Does the output of "date" and "hwclock" show the same time? If you boot your system with init=/bin/sh, do "date" and "hwclock" match? This will test if your kernel is setting the clock on boot before init starts.
They do: berlioz ~ # hwclock ; date lun 30 mar 2015 19:49:30 CEST .921546 seconds lun 30 mar 2015, 19.49.30, CEST Will try with init=/bin/sh on next reboot and report. I got this option in kernel : CONFIG_GENERIC_CMOS_UPDATE=y, you think it could interfere, right .. ?
Well, I'm thinking of two possibilities: 1. CONFIG_RTC_HCTOSYS is not set, so the kernel does not set your system clock on boot. The system clock would then default to Jan 1 1970. This seems unlikely, given the "less than a day" message, but maybe fsck is lying about that due to some bug. 2. Some init script(s) are messing up your system clock before fsck, and fixing it afterwards. I'm not sure how this could happen.
(for the record) CONFIG_RTC_HCTOSYS seems ok. orzel@berlioz /home/orzel% zgrep RTC_HCTOSYS /proc/config.gz CONFIG_RTC_HCTOSYS=y CONFIG_RTC_HCTOSYS_DEVICE="rtc0"
Still, please check your BIOS date before booting Linux and compare it to the real time. At least this will help to understand when your time is messed up: during OS boot or before/at shutdown. Also please disable your NTP client/server (if any) for testing and post the following: 1. BIOS time 2. Time reported by fsck 3. Time just after your system is booted. And compare them with some external clock for that exact moments. P.S. I still have no idea even whom to assign this issue...
(In reply to Andrew Savchenko from comment #14) > I still have no idea even whom to assign this issue... Thus far, no "bug" has been identified, so there's really nobody to assign it. If a bug is not identified, we close it as NEEDINFO.
Some more thoughts... (In reply to Thomas Capricelli from comment #0) > For the last few weeks (maybe months), my main desktop computer does fsck on > all (but one) partitions on every reboot. Can you find in logs after what action this had happened? Maybe some package was updated or kernel. Could you please update kernel, e2fsprogs and openrc to the latest versions available and see if bug is still here?
Well, we have the problem: fsck is being run after each reboot. Though we don't know where this problem originates from. My guess is that one of the following components may be responsible: - fsck (e2fsprogs); - base init scripts (openrc); - kernel. So I'm assigning/CC'ing relevant teams. Maybe they have some new ideas. Thomas, please provide information requested in comment 16. This should help to rule out some reasons.
(In reply to Andrew Savchenko from comment #16) > Can you find in logs after what action this had happened? Maybe some package > was updated or kernel. I update both system (gentoo) and kernel very regularly, wont teach us much. > Could you please update kernel, e2fsprogs and openrc to the latest versions > available and see if bug is still here? Already at last versions (as i update often). Anyway, i dont think the bug is in one of those packages. Regarding your comment #14, i dont know how what is the "time reported by fsck". The date/time in bios is correct afaics (usual UTC time, as it has always been). I've noticed that the CONFIG_RTC_DRV_CMOS kernel stuff was configured as module, and I'm investigating if having it compile-in could solve the problem. I set "in progress" as anyway i'm more and more convinced that this is a configuration problem of my own and not a bug in some gentoo package.

So if you know when this bug appeared for the first time, you can find in a log after update of what package(s) this happened. This may help to find what triggered the issue. > Regarding your comment #14, i dont know how what is the "time reported by > fsck". When fsck is complaining: "Superblock last write time is in the future (by less than a day, probably due to th hardware clock being incorrectly set)" Does it show exact timestamp for what time is in future? > I've noticed that the CONFIG_RTC_DRV_CMOS kernel stuff was configured as > module, and I'm investigating if having it compile-in could solve the > problem. Modules are loading after fsck, so this maybe indeed the reason.
The problem is still there with RTC driver built-in. The problem is also here after the computer is several hours down, so it's not utc-related (i'm at utc+2 hours here). I don't know precisely when the bug appeared, genlop wont help. I'm not even sure it's a installed/updated gentoo package that triggered this.
(In reply to Andrew Savchenko from comment #19) > When fsck is complaining: > "Superblock last write time is in the future (by less than a day, probably > due to th hardware clock being incorrectly set)" > Does it show exact timestamp for what time is in future? Of course not, that would have helped a LOT for sure .. I tested again and everything seems fine * when booting into bios, the date/time is the right utc one (here minus 2 hours) * booting with init=/bin/bash, I confirm hwclock/date give the same time, which is the right time (utc+2) * still in this session, "dumpe2fs -h" gives totally normal information. The "Last write time" is when i shut the computer down. The error message by e2fsck mentions "Superblock last write time" but i dont know how to get this exact date. dumpe2fs only reports "Last write time"
Fixed, was rather a configuration problem. For the record, the default gentoo settings give this behaviour when using ntpd. If so, you need to change /etc/conf.d/hwclock with: clock_hctosys="no" clock_systohc="no"
