Quickboot no command12/16/2023 Boot your device into fastboot mode/bootloader mode.ADB and Fastboot installed on your system.To make it easier, we’ve added a short description, syntax and an example. To execute the below mentioned commands, you’ll also need to have Fastboot installed on your computer system, You can follow our guide to install ADB and Fastboot for the installation. Now that you have Fastboot working on your system, you can check the below commands. These are probably the most useful tools available which will come to rescue when you brick your device or when you want to replace your device partitions. As mentioned above, the Fastboot commands would work even if the OS isn’t booted, provided your device is booted into Bootloader/Fastboot mode. Hence, the Android debugging tools can’t communicate to the phone. When you’re working on the bootloader mode, ADB commands will no longer work, as the device is not booted into Android OS. Fastboot Reboot/reboot-bootloader commands.So it A) failed to do its job and B) the code that was running could no longer find its dependent code fragments so … watch out. Naturally when one of the real drives got sick the hotswap script took over – changed the fs layout but could not do much because the drive had active connections to parts of the disk. The only case I know of where this caused a lot of problems was when someone had perforce assumed control of a hotswap drive and had partitioned it up and was running executables on it. If you have a hotswap drive installed you may have complications – as a drive group with a hotswap may take some time (appearing to be locked up and non-responsive when in fact it is very busy laying down a new fs on the hotswap drive). Different version of the LINUX kernel support different options – check out BSD versus LINUX versus AIX or Solaris. C) as indicated you can change things with fastboot or by modifying /etc/fsck either with grub or with a mounted “/etc/fsck” fs – which may require a ‘mount -o rw,remount /’. B) some filesystems will always run a fsck, mind you a quick one, whenever you try to mount a filesystem these are mostly the more modern filesystems. A) most filesystems allow for tune2fs to modify parameters – one method of checking is “number of days since last check” and the other is “number of mounts since last check” – so you can choose the method in most cases. OK the ways and means of stopping a fsck from happening at boot time are a little bit more complex. Here is sample entry: LABEL=/disk3 /disk3 ext3 defaultsĐ 0 If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. The sixth field, is used by the fsck program to determine the order in which filesystem checks are done at reboot time. This will have the system mount the partition but will not run a check when booting. You will see two numbers at the end of the line for each partition, change the second number to a 0 (zero digit). Kernel /vmlinuz-2.6.18-92.1.22.el5 ro root=LABEL=/ console=tty0 console=ttyS1,19200n8 fastboot Skip fsck by updating /etc/fstab fileįinally, you can edit /etc/fstab file which, contains descriptive information about the various file systems. Open nf or menu.lst (usually located in /boot),įind kernel line and put fastboot at the end of the kernel line. Set Linux kernel option by editing nf / menu.lst When rebooting the server use the following commandĪbove command will reboot the system and will not run auto fsck.
