Solaris 7/8 - journaled file systems?

Do I need to do anything to enable this feature? I don't see any references to file system journaling on any man pages. Can I convert ufs file systems?, etc, etc ...

Yes, you have to mount the filesystems with option 'logging', see the
mount_ufs(1M) man page. Using the 'remount' option in combination
with 'logging' or 'nologging' you can turn it on/off on a mounted
filesystem. To enable it across a reboot, add the 'logging' option
into the last (= mount options) column for the relevant line in
/etc/vfstab.

  • Journaled file system for startup volume only?

    I have been told that the advantage of a journaled file system is only realized on the startup volume. Surely, protecting the critical startup files is first priority for most users, but does the advantage of a journaled file system apply to other drive volumes, too? Please explain why this is or is not true. Thanks.

    it applies to all drives but it's much less relevant for non startup drives. startup drives are being written to constantly and other drives are not. the likelihood of an external drive being written to at the moment of say a power outage is much smaller than that for the startup drive. therefore having journaling on on nonstartup drives is not as crucial. you can still do it though if you want to.

  • PSA: Do you remember a time before journaled file systems? (netbooks)

    I didn't either.  So when I read "You should format your SSD-based netbook with ext2 because journals write too much and SSDs have a write limit," I thought, "Seems logical.  What could go wrong?"
    Apparently I didn't remember the dark ages, when men were men and a power failure meant you lost your partition table.
    So I'm having a BLAST with my new dell mini, and reading this guide, and it says to load a hotplug module for your SD cards.  I wonder, as any computer scientist would, whether it was really hotpluggable with this driver loaded.  So I put an SD card in, formatted it with ext2, mounted it, and proceeded to remove it from the system.
    Freeze!
    Guess it's not so hotpluggable.
    Reboot.
    No root filesystem.
    Actually, it was there, but most of the files were either zeroed out or acted as if they had never been edited, i.e., blissfully newborn rc.conf, complete with defaults.
    So, use journals.  It's formatted with ext3 this time.

    FAT (or HFS) isn't journaled, everytime pre-Win2k crashed it required a full ScanDisk which took ages! ext2 is the same, although since it's a SSD that isn't that much of a problem.
    Depending on the nature of the crash a journal might not have saved you from that. Just because it has a journel doesn't mean the partition table won't be dumped.

  • 8.1.7EE certified for which file systems on RedHat 7.1 ?

    Hi,
    Does anybody know if Oracle 8.1.7 Enterprise Edition is certified for
    any other file systems than ext2 (and raw) on RedHat 7.1.
    Specifically journaling file systems, e.g., ReiserFS, XFS, ext3.
    Thanks in advance,
    /Leif Klepp

    Well I think the problem is at Sun, not at us, but I couldn't figure out how to contact them for this particular problem. I hope they will someday notice this topic and fix the problem or, if we are doing something wrong, say what else requirements we have to meet :).

  • How to make OS-X recognize ext4 file systems

    Hi:
    Is there a way to have OS-X recognize and access (read/write) a disk that is formatted with ext4 (journaling) file system? Thanks.

    Thanks for the info, but the exercise to make is too technical fo me. Maybe
    Paragon extFS  could help, but  my project goes beyond that.  I want to read/write files from an ext4 formatted drive, but I also want to boot the Linux OS that resides in the drive. I haven't found a single solution for this yet, except using virtualization.

  • Format Error : mkfs.ocfs2 1.2.7 file system too small for a journal

    Hi All,
    I am trying to implement Oracle 10g RAC on my laptop using vmware and openfiler software . But while executing the command
    #mkfs.ocfs2 -b 4K -C 32K -N 4 -L oracrsfiles /dev/iscsi/crs11/part1
    I am getting the error
    Format Error : mkfs.ocfs2 1.2.7 file system too small for a journal
    Please anybody can help me to resolve this problem.
    Thanks in Advance.

    How large is the device that you are formatting?
    The default journal size depends on the type specified. If none specified,
    then it assumes "mail" which sets the default journal per slot to 256M.
    If database type, default is 64M.
    Use "-T database" to specify database type, etc.
    BTW, one can always override the defaults. Say "-J size=16M" to make
    a smaller journal.
    man mkfs.ocfs2 and the user's guide has more.

  • How so I protect my root file system? - x86 solaris 10 - zfs data pools

    Hello all:
    I'm new to ZFS and am trying to understand it better before I start building a new file server. I'm looking for a low cost file server for smaller projects I support and would like to use the ZFS capabilities. If I install Solaris 10 on a x86 platform and add a bunch of drives to it to create a zpool (raidz), how do I protect my root filesystem? The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too? or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Should I install solaris 10 on a mirrored set of drives? Can the root filesystem be zfs too? I'd like to be able to use a fairly simple PC to do this, perhaps one that doesn't have built in raid. I'm not looking for 10 terabytes of storage, maybe just four 500gb sata disks connected into a raidz zpool.
    thanks,

    You could use Sun Volume Manager to create a mirror for your root filesystem.
    The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too?No. They're separate filesystems.
    or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Yes. (Actually, you can import the ZFS pool you created).
    Should I install solaris 10 on a mirrored set of drives?If you have one, that would work as well.
    Can the root filesystem be zfs too?Not currently in Solaris 10. The initial root support in OpenSolaris will require the root pool be only a single disk or mirrors. No striping, no raidz.

  • Unbootable Solaris 10 x86 installed on ZFS root file system

    Hi all,
    I have unbootable Solaris 10 x86 installed on ZFS root file system. on an IDE HDD
    The bios keep showing the msg
    DISK BOOT FAILURE , PLEASE INSERT SYSTEM BOOT DISK
    please note :
    1- the HDD is connected properly and recognized by the system
    2- GRUB don't show any messages
    is there any guide to recover the system , or detail procedure to boot system again
    Thanks,,,

    It's not clear if this is a recently installed system that is refusing to boot OR if the system was working fine and crashed.
    If it's the former, I would suggest you check the BIOS settings to make sure it's booting from the right hard disk. In any case, the Solaris 10 installation should have writting the GRUB stage1 and stage2 blocks to the beginning of the disk.
    If the system crashed and is refusing to boot, you can try to boot from a Solaris 10 installation DVD. Choose the single user shell option and see if it can find your system. You should be able to use format/devfsadm/etc to do the actual troubleshooting. If your disk is still responding, try a `zpool import` to see if there is any data that ZFS can recognize (it usually has many backup uberblocks and disk labels scattered around the disk).

  • Solaris 10 - File System Size / Layout

    Hello, I�m very new to Solaris OS � UNIX world and have a question around the file system.
    I have SUN System with a single 36GB of Hard Disk, and eventually I want to install Oracle 10g on it as a development server for myself.
    My question is around the file system size and layout
    I have installed Solaris 10 and accepted the default file system, which is as below:
    Filesystem size used avail capacity Mounted on
    /dev/dsk/c1t1d0s0 5.0G 3.4G 1.6G 69% /
    /devices 0K 0K 0K 0% /devices
    ctfs 0K 0K 0K 0% /system/contract
    proc 0K 0K 0K 0% /proc
    mnttab 0K 0K 0K 0% /etc/mnttab
    swap 1.5G 1.1M 1.5G 1% /etc/svc/volatile
    objfs 0K 0K 0K 0% /system/object
    /platform/sun4u-us3/lib/libc_psr/libc_psr_hwcap1.so.1 5.0G 3.4G 1.6G 69% /platform/sun4u-us3/lib/libc_psr.so.1
    /platform/sun4u-us3/lib/sparcv9/libc_psr/libc_psr_hwcap1.so.1 5.0G 3.4G 1.6G 69% /platform/sun4u-us3/lib/sparcv9/libc_psr.so.1
    fd 0K 0K 0K 0% /dev/fd
    swap 1.5G 136K 1.5G 1% /tmp
    swap 1.5G 88K 1.5G 1% /var/run
    /dev/dsk/c1t1d0s7 28G 28M 28G 1% /export/home
    What I don�t understand is when I eventually install Oracle, where will the directory go for it?
    The /home/export folder is aprrox: 28GB which is now taking up most of the space, and I understand that this is for users, therefore my question is:
    1.Should I have allocated a more space to the root file system for oracle during the OS install?
    2. If so what should I do? (its not a production system and I know it will have to go somewhere on the single drive, I�m happy to rebuild as I�m still learning the OS).
    Any suggestions?
    Rgds
    D

    Thanks, I do have this but needed info on the file system layout... but I have the info now...
    If you select the auto file system layout on Solaris 10 then it gives the remaining space to the home/export . I have since re-installed, customised the file system layout and have space for the database.

  • How do you expand a file system on Solaris 10 that is running as a LDOM on Solaris 11

    I'm somewhat new to Solaris but needing to expand an existing file system /work on our solaris 10 ldom that was P2V'd into a Solaris 11.2 environment.  I also have several additional questions that I can't seem to find an answer for anywhere.
    When trying to expand the disk device using the "format" command, when you get to the partition and it asks you to "Enter partition size(147456b, 2c, 3891e, 72.00mb, 0.07g]:" what does the "b" "c" "e" sizes indicate and why and when would you use them?   It seems that you would want to always just add size based on MB or GB?
    When trying to use "growfs" after I increased a partition on a disk, I get error devinfo: /dev/dsk/c0d0s7: Inappropriate ioctl for device, growfs: cannot get partition size.  What step have I missed?

    Matt--
    One suggestion: if you can't figure out how to put a file system on the empty space, you could clone your current partition to an external drive, re-partition the internal drive drive and then clone the external back. Like John, I've heard of utilities that can re-partition a drive without erasing your data, but I just can't imagine using one if I didn't have a clone anyway. So that's what I've done when I want to change a partition size.

  • Udfs file system on Solaris 10

    hello all,
    cannot find the limit of udfs file system on solaris 10.
    Which is the med a block size that can be used ?
    ANy chance to create udfs on 8192 block size media ?
    Thanks
    Aldo

    First check the mkfs_udfs((1M) manualpage, it displays some information regarding this. Next you may benefit from the fsdb_udfs(1M) command to display certain options. But with regards to blocksize and the likes the first manpage should do.
