resize root partition in solaris 10 - down time is required

resize root partition in solaris 10 - down time is required

     -  A 146 GB disk is completely assigned to c0d0s0 slice as root file system
     -  Need to split the slice to have another 20GB slice as c0d0s1 and mount it as /data

1. Add a temporary disk c1d0s0 and mount in /mnt

2. create ufs dump of root slice to a file in the temporary disk
ufsdump 0uf /mnt/rootbkp.ufs /dev/dsk/c0d0s0

3. shutdown the server and boot the server using cdrom or ISO for ldoms
boot cdrom1

4. format the disk and create 120GB space in c0d0s0 slice

5. format the disk and create a 20GB space in c0d0s1 slice

6. label the disk and quit

7. create new FS in c0d0s0 slice
newfs /dev/rdsk/c0d0s0

8. Create new fs in c0d0s1 slice
newfs /dev/rdsk/c0d0s1

9. Mount the c0d0s0 in /a
comment out "/" in /a/etc/vfstab
mount /dev/dsk/c0d0s0 /a

10. mount the temporary disk c1d0s0 in /mnt
mount /dev/dsk/c1d0s0 /mnt

11. restore the dump in root slice c0d0s0 from file
ufsrestore rf /mnt/rootbkp.ufs /a

12. install the boot block to make available the disk as boot disk
installboot /a/usr/platform/sun4v/lib/fs/ufs/bootblk /dev/rdsk/c0d0s0

13. edit and un comment the "/" in /a/etc/vfstab

14. add the below line in /a/etc/vfstab to mount the c0d0s1 slice as /data_stuff
/dev/dsk/c0d0s1    /dev/rdsk/c0d0s1    /data_stuff    ufs     2       yes     logging

15. boot the server in normal mode, server will boot in c0d0 disk,

nfs share using zfs and mounts options

nfs share using zfs and mounts options

1. Create a zfs volume and mount as /data_stuff
zfs create -o mountpoint=/data_stuff rpool/data_stuff

2. set quota for 20GB - This volume has restricted to 20GB not more than that
zfs set quota=20G rpool/data_stuff

3. Reserved dedicated 20GB space in rpool for the zfs data_stuff, other volumes cannot use this space
zfs set refquota=20G rpool/data_stuff

3. Share the zfs as nfs
zfs set sharenfs=on rpool/data_stuff

4. Set nfs permisssion for the zfs
zfs set share=name=some_description,path=/data_stuff,prot=nfs,anon=0,sec=sys, \
rw=@192.168.0.1:@192.168.0.2,root=@192.168.0.2:@192.168.0.2 rpool/data_stuff

5. View the config updated automatically in /etc/dfs/sharetab
/data_stuff  some_description   nfs     anon=0,sec=sys,rw=@192.168.0.1:@192.168.0.2,root=@192.168.0.2:@192.168.0.2

6. Entry in vfstab to mount a nfs share
judi-test-01:/vol/Oracle_migration/Oracle      -             /Oracle_migration          nfs       -        yes       -

zpool attach rpool c2t5000CCA07047CEB9d0 c6t5000CCA07047E089d0

2. Check the status for resilvering
zpool status rpool

3. Apply boot blocks to the second disk after resilvering is complete
installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/<new-device>
installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c6t5000CCA07047E089d0

Create new zpool and zfs filesystem

1. Create a new pool name ldom1 that consists of disk c1t0d0
zpool create ldom1 c1t0d0

2. Create a new pool / zfs in same name and mount it - single command
zpool create -f -m /opt/oracle opt_oracle c1d1

3. Create new zfs in a existing pool
zfs create -o mountpoint=/opt/oracle/ora opt_oracle/ora

4. Destroy a zpool
zpool destroy opt_oracle

5. To View / List the zfs snapshots zfs list -t snap 6. Delete a a zfs snapshot ; user -R for cloned snapshot zfs destroy -R rpool/ROOT/solaris

Network driver version

Verify the Driver Version (Oracle Solaris 11)

              strings /kernel/drv/<arch>/igb | grep igb 

              where arch is amd64 for 64-bit Intel systems or sparcv9 for Oracle SPARC systems.

              strings /kernel/drv/sparcv9/ixgbe  | grep ixgbe

                            ixgbe 1.1.59

                                          If the version number is not at least 1.1.9, you must install the latest driver, 

              strings /kernel/drv/sparcv9/igb  | grep igb

                            igb 2.3.19

Quota in Solaris 10 UFS

Quota in Solaris 10 UFS

1.    Copy /etc/vfstab configuration file
               cp -p /etc/vfstab /etc/vfstab-`date +%d-%b-%Y`

2.    Edit the /etc/vfstab file and add an "rq" in mount option for the FS you like to enable quota
               /dev/dsk/c0d0s0 /dev/rdsk/c0d0s0        /       ufs     1       no      rq

3.    Here we enabled quota in root "/" FS
Use the mount command and make available the quota option online
               mount -o remount,quota /

4.    Get into root directory of the respective FS ( here / is the FS )
               cd /

5.    Create a file name quotas and change the permission
               touch quotas
               chmod 600 quotas

6.    edquota is a editor command for updating quotas ( here the user is judi)
               edquota <user-name>
               edquota judi

7.    Update the soft and hard lmit values in blocks ( here given is 2 GB - 2097152 blocks
               fs / blocks (soft = 2097152, hard = 2097152) inodes (soft = 0, hard = 0)

8.    Enable the quota for "/" FS
               quotaon -v /

9.    Login to the user or switch that user and see
Now try to write data more than 2GB, It will not allow us to write
                 $ /usr/sbin/mkfile 1g file1
                 $ /usr/sbin/mkfile 800m file2
                 $ /usr/sbin/mkfile 500m file3
                                quota_ufs: over hard disk limit (pid 29154, uid 120, inum 298862, fs /)
                                file3: initialized 233783296 of 524288000 bytes: Disc quota exceeded
                $
                 $
                 $ du -sh .
                      2.0G   .
                 $

10.   The quota command display a user’s ufs file system disk quota and usage
               quota -v vivek

11.   The repquota command displays a summary of the disk usage and quotas for the specified ufs file systems such as /export/home, enter:
               repquota /export/home

12.   To display quota information of all users, type:
               repquota -va


We will get an error in /var/adm/messages
Oct  3 17:01:48 judi-test-01 genunix: [ID 800400 kern.notice] quota_ufs: over hard disk limit (pid 10644, uid 120, inum 298868, fs /)
