Booting Problems [Likely Solved]

Post by VolvoBirkenstock » Sun Apr 08, 2018 19:57

Hello, Sabayon Gurus.
I don't believe this is a Sabayon or a Linux problem, but I am hoping for an explanation.

I have a system that is dual-bootable to Win7 and Sabayon. Last time I was in Win7, I was abused by the BSOD and could hear the hard drive buzzing/vibrating in a strange manner. Subsequent to this event, the machine will not boot in the usual manner. I can boot it using a Sabayon Live DVD. I can boot it using a Win7 DVD. But here is the strange part:

If I insert the Win7 DVD and boot, I am prompted with a message something like "press any key to run the DVD......" If I do nothing, in a few moments I am greeted with the choice provided by grub, and I can boot into either Win7 or Sabayon. I guess this work-flow must allow the system to work-around a damaged area of the disk.

Can you explain this behavior to someone who really doesn't know much about the intricate details of the boot process?

I note that if I insert the Sabayon Live DVD and boot, I am not prompted with this message but instead load the DVD.

One more thing: I see the following message returned by "dmesg" in Linux:

Code: Select all

[   20.591304] udisks-lvm-pv-e[2298]: segfault at 0 ip 0000557b73d7d069 sp 00007fff5939cb30 error 4 in udisks-lvm-pv-export[557b73d7c000+2000]
Shall I assume that my hard drive is truly hosed? I did run the Sabayon Live DVD, mounted the hard drive, and backed everything up from both Win7 and Sabayon onto an external hard drive.

Edited to add: I should mention that the SMART Data is providing the overall assessment of "Disk is OK".

Thank you very much in advance.

I suspect that WinBlowz 7 overwrote an important region of my hard drive, thereby damaging the normal boot process. Here are the results from an extended multi-hour smartctl run with output displayed with "smartctl -x":

I've read "man smartctl" but the interpretation of some of the above output is not intuitively obvious to me. Is there something wrong here? Is the hard drive too old to be reliable? Seriously? Am I being warned about "prefailure" as though the drive is about to degrade or die?

Also please let me know if there are any potential security issues with my release of the above smartctl output.

Thank you very much in advance.

Please provide some information on your installation.

1. PC BIOS or UEFI?
2. MBR or GPT HDD?
3. Is /boot directory on same partition as / (root)?
4. What partitions are used (/dev/sda, /dev/sdb and so on)), and what is on them (/, /boot, /home, etc.) Use the blkid command as root user to see.

Hello, Fitzcarraldo. Thank you for your response.

Answers to your questions in your order.
Information obtained using Linux utilities, where needed.
1. UEFI.
2. The partition table is "msdos", so I assume that is "MBR".
3. /boot is on a different partition than "/". (If I recall correctly, this was the default Sabayon configuration when I performed the LFC approximately 1.5 years ago.)
4.

/dev/mapper/sabayon_fuutkraamp-home: UUID="4e1bd30f-5d19-4997-8a6e-35cf71aaba7d" TYPE="xfs"
I believe that "/" is on the logical volume /dev/sabayon_fuutkraamp/root, /home is on the logical volume /dev/sabayon_fuutkraamp/home, and /boot is on the /dev/sda3 partition. I believe this was the Sabayon default when I performed the LFC.

I know that XFS is not the Sabayon default file system, but I chose to use this based on past experience and the recommendation of several people I know well.

Again, thank you very much for your time and expertise, Fitzcarraldo. Does this provide you with all of the information you need?

You've formatted /boot partition with XFS filesystem .

Please read :
https://en.wikipedia.org/wiki/XFS
RHEL 7.0, released in June 2014, uses XFS as its default file system, including support for using XFS for the /boot partition, which previously was not practical due to bugs in the GRUB bootloader.

Q: Does GRUB work with XFS?

There is native XFS filesystem support for GRUB starting with version 0.91 and onward. Unfortunately, GRUB used to make incorrect assumptions about being able to read a block device image while a filesystem is mounted and actively being written to, which could cause intermittent problems when using XFS. This has reportedly since been fixed, and the 0.97 version (at least) of GRUB is apparently stable.
(for Grub-legacy and Grub2)

So there are some patches provided by RHEL for /boot partition XFS formatted. Not sure if Grub is patched for this.



I'm running XFS on my sabayon system (for my /home and backup LVM partitions) and my partitions layout is :

Re: Booting Problems

Thank you for your response, Sabayonino. I do not claim to fully understand what you are telling me.

I am apparently running grub 2.02_beta3-r1.

Are you telling me that the BSOD seen in Windows which resulted in an inability to directly boot from grub into either Windows or Linux is because my /boot partition is XFS?

I still do not understand why placing a Windows Live DVD into the DVD drive, allowing it to spin up during system power-on, and then waiting for it to time out, subsequently allows grub to present a choice of Windows or Sabayon Linux.

My motherboard provides UEFI. When I first loaded Sabayon Linux onto this system with an ISO image loaded on a USB memory stick, it imposed /boot/efi on the system, and I had great difficulty attempting to dual boot. I eventually gave up on that, and instead loaded Sabayon Linux from Live DVD. I note that the installation from Live DVD did not impose a /boot/efi. /boot/efi does not exist on my Linux system.

I am apparently unable to repair the apparent damage caused during the Windows BSOD using the Windows repair mechanism on the Windows installation disk.

I would like to know/understand root cause before taking action. I would like to know if my hard drive has been irreparably damaged. I would like to know if I need to reinstall a dual bootable configuration on a new hard drive. The information you provided concerning XFS implies that grub and XFS might not have any issues given that grub 2.02_beta3-r1 greatly exceeds legacy 0.97. However, if I need to rebuild a dual bootable configuration, are you telling me to NOT use XFS for /boot?

This raises another question: Is there any simple cook-book recipe for dual-booting with UEFI? Again, as I wrote above, I had significant difficulty but found a method that worked by performing load-from-cold with only Live/Installation DVDs.

Thank you very much in advance.

UEFI implies a FAT32 /boot/efi partition and GPT to boot >=Windows8

I have been dual booting between Linux and Win7. The motherboard is UEFI.

1. Based on this information, are you now saying that I incorrectly formatted the hard drive?
2. Are you now saying that I still needed a FAT32 /boot/efi partition?

If I performed task 1 and 2 listed above incorrectly, then why did the Sabayon Live DVD load-from-cold _not_ force these rules or instruct me that it could not pursue load from cold until I resolved this? Again, other than the choice of XFS, pretty much everything I recall doing used the Sabayon defaults.

Installing from a memory stick forced /boot/efi, but I could not get dual-boot to work, so I fell back upon an install from Live DVD.

Understand that I have had no problems with booting since that load from cold late in 2016, and I've only experienced a problem with dual boot subsequent to a BSOD inside Win7. Are you implying that the BSOD was due to XFS used on /boot? If so, how does Win7 impact data on /boot?

Sorry, I'm not trying to be obtuse. I don't mean to frustrate or anger anyone. I'm just trying to understand what really went wrong so I can correct the issue.

I am marking this as "Likely Solved". I apologize for wasting everyone's time, but I suspect that I now know at least part of the root cause.

You may recall that I mentioned that there was a BSOD while in Win7, and that there was a vibrating/buzzing sound. I assumed that the hard drive had been damaged or a portion of the boot sector had been overwritten. It turns out that was not the cause.

I tried to boot today in the usual new way, using the Win7 DVD for load from cold (LFC) and waiting for it to time out, and then failing over to grub on the hard drive. Today it did not do that. Today it hung at a screen before it got to grub. The screen very slowly reported something like:

Code: Select all

AMD AHCI BIOS Version 3.0.5
AHCI Drive Init ...
ID  Device Attached
----------------------
<listed the DVD drive here>
<listed the hard drive here>
and then no progress was made. So maybe I am seeing some motherboard or other hardware/functional degradation. But I digress...

I then attempted to reboot, but I forced the UEFI graphical display to open, and then I observed the device boot order. I was very surprised to see that the order had changed from my previous settings. I suspect (but do not know) that this reordering occurred during all the buzzing/vibrating during the Win7 BSOD.

The configuration for boot order was supposed to be (1) DVD drive, (2) hard drive, (3) EFI shell. Instead it had been reordered to (1) DVD drive, (2) EFI shell, (3) hard drive. Returning the boot order to the former configuration now allows me to dual boot without using the Win7 LFC DVD and waiting for it to fail over to the hard drive.

Even so, I suspect that there is still an issue, either with the motherboard, or wiring connectivity, or a failing hard drive, but at least I don't need to depend on the DVD for a fail-over event.

Again, I apologize for consuming your time with this.

I don't know about Windows BSOD , it's not Sabayon related.

If you're thinking you've hardware failures (hdd ? ) before to buy/change the harddrive check all data connections (data cable) or try to change sata port and check the power supply.
