Hello,
I use Sun Solaris 10 under a x86 computer, and I want to mount a Fat32 partition who are stored in the same disk with the UFS filesystem.
But, before mount this partition, I need to know is location in /dev/dsk
Because there are a lot of file "c0t0d0" etc..., and I didn't find my... (4 Replies)
Hi there
I am about to mirror a Solaris 10 x86 box (SunFire X4100) onto a secondary disk using svm (current system is one disk). My question is this, on X86 boxes there is a slice 8 defined as boot partition (and also a slice 9, dunno what its used for tho). Do I need to mirror this boot slice... (0 Replies)
Dear Folks
Is there anyway to give a UUID to a swap partition? mkswap on CentOS 5 (util-linux-2.13-0.45.el5_1.1) appears to override this option ;-(
# swapoff -a
# mkswap -L swap1 /dev/sda3
Setting up swapspace version 1, size = 4293591 kB
LABEL=swap1, no uuid
And there's no... (3 Replies)
Hello Experts,
Is there a way to generate Universally Unique identifiers on all Unix flavours such as Solaris, RHELinux,Suse Linux, MacOS,HP UX etc?
If i can get a system command or a system call or an algorithm/script/program to generate a unique identifier, it will be helpful.
Thanks in... (1 Reply)
How do we find the partition type in Linux? df -T will give me the mounted partition types like ufs, ext3 etc. How do I find out for say a newly added disk to the system? Please advise...
Thanks (2 Replies)
HI, I'm trying to find the unallocated space in console mode from my hard disk. I tried " df-hk and fdisk" commands, but either of the commands are not listing out the unallocated space. It's just listing the existing partition. please let me know how to list that and partition that in text mode. (3 Replies)
Hi all,
I am using SPARC Solaris 11.1 with EFI labelled disks.
I am new to ZFS file systems and slightly stuck when trying to create a partition (slice) on one of my LUNs.
EFI labels use sectors and blocks and I am not sure how exactly it works.
From here I can try and create a... (2 Replies)
I have a laptop I'm setting up to multi-boot between Win 7, Solaris 11, Ubuntu 14.04, and CentOS 7. I have a common FAT32 partition for all of them to save data to. I'm less familiar with Solaris and haven't used it in years, and am really struggling :-)

jfs_tune
jfs_tune(8) Set JFS file system parameters. jfs_tune(8)NAME
jfs_tune - adjust tunable file system parameters on JFS
SYNOPSIS
jfs_tune [options] device
DESCRIPTION
jfs_tune adjusts tunable parameters on a Linux JFS file system or external journal. jfs_tune must be run as root.
device is the special file name corresponding to the actual device (e.g. /dev/hdb1) on which a JFS file system or JFS external journal has
been created.
OPTIONS -J device=external-journal
Only supported on JFS versions (1.0.18 or later) that support external journal. Attach the JFS external journal located on exter-
nal-journal to the JFS file system on device.
Currently, you may only attach a single JFS file system device to a single JFS external journal (i.e. each JFS file system using an
external journal must have a unique external journal).
The external journal must already have been created using the command
mkfs.jfs -J journal_dev external-journal
Attach the external journal to the file system by using the command
jfs_tune -J device=external-journal device
Instead of specifying a device name directly, external-journal can also be specified by either LABEL=label or UUID=UUID (Use
jfs_tune -l device to display a journal device's volume label and UUID.)
-l List the contents of the JFS file system or external journal superblock that resides on device.
-L volume-label
Set the volume label of the JFS file system or external journal. JFS labels can be at most 16 characters long; if volume-label is
longer than 16 characters, jfs_tune will truncate it and print a warning. The volume label can be used by mount(8), fsck(8), and
/etc/fstab(5) (and possibly others) by specifying LABEL=volume_label instead of a block special device name like /dev/hda5.
-U UUID
Set the universally unique identifier (UUID) of the file system or external journal device to UUID. The format of the UUID is a
series of hex digits separated by hyphens, like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The UUID parameter may also be one of
the following:
clear clear the file system UUID
random generate a new randomly-generated UUID
time generate a new time-based UUID
The UUID may be used by mount(8), fsck(8), and /etc/fstab(5) (and possibly others) by specifying UUID=uuid instead of a block spe-
cial device name like /dev/hda1.
See uuidgen(8) for more information.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Set a randomly-generated UUID for the JFS file system on the 3rd partition of the 2nd hard disk, and view the resultant superblock:
jfs_tune -l -U random /dev/hdb3
Attach an already existing external journal on a device labeled JFSLog to a JFS file system on /dev/hda8:
jfs_tune -J device=LABEL=JFSLog /dev/hda8
