Lvmraid

grace a lvm et raid1 par defaut sur sme vous pouvez gerer facilement les disques, voir meme changer un disque ou deux et retoucher la taille des partitions.

resumé Upgrading the Hard Drive Size

   * CAUTION MAKE A FULL BACKUP!
   * Ensure you have e-smith-base-4.16.0-33 or newer installed. [or Update to at least 7.1.3] 

  1. Shut down and install larger drive in system.
  2. Boot up and manage raid to add new (larger) drive to system.
  3. Wait for raid to fully sync.
  4. Repeat steps 1-3 until all drives in system are upgraded to larger capacity.
  5. Ensure all drives have been replace with larger drives and array is in sync and redundant!
  6. Issue the following commands:
        1. mdadm --grow /dev/md2 --size=max
        2. pvresize /dev/md2
        3. lvresize -l +$(vgdisplay -c main | cut -d: -f16) main/root 
           ou   lvresize -l +$(vgdisplay -c vg_primary | cut -d: -f16) vg_primary/lv_root

[-l (lower case L)]

        4. ext2online -C0 /dev/main/root 

[is -C0 (zero)]

Notes :

   * All of this can be done while the server is up and running with the exception of #1.
   * These instructions should work for any raid level you have as long as you have >= 2 drives
   * If you have disabled lvm 

  1. you don't need the pvresize or lvresize command
  2. the final line becomes ext2online -C0 /dev/md2 (or whatever / is mounted to) 

resize machine vmware

d'abord:

C:\Program Files\VMware\VMware Server>vmware-vdiskmanager -x 8GB "F:\Documents\M

y Virtual Machines\VMWP-SME7\sme7pre1.vmdk"

C:\Program Files\VMware\VMware Server>vmware-vdiskmanager -c -s 8GB -a ide -t 1
"F:\Documents\My Virtual Machines\VMWP-SME7\sme7pre2.vmdk"

puis modifier le fichier de la machine pour ajouter le disque

ensuite meme chose que ajout de disque

1. Freeing /dev/sda:
2. First, removing all RAID1 partitions on /dev/sda:

mdadm /dev/md1 --fail /dev/sda3 --remove /dev/sda3 mdadm /dev/md0 --fail /dev/sda1 --remove /dev/sda1

1. Then, stopping the swapspace on /dev/sda:

swapoff /dev/sda2

1. Then, altering the partition tables:

fdisk /dev/sda

 #entering 'w' at the end to write. This should go OK now.

1. Start using the partitions again:

swapon /dev/sda2 mdadm /dev/md0 --add /dev/sda1 mdadm /dev/md1 --add /dev/sda3

1. wait for both md devices to be fully synced
2. (check /proc/mdstat)

1. same with /dev/sdb

mdadm /dev/md1 --fail /dev/sdb3 --remove /dev/sdb3 mdadm /dev/md0 --fail /dev/sdb1 --remove /dev/sdb1 fdisk /dev/sdb mdadm /dev/md0 --add /dev/sdb1

1. don't add /dev/sdb3 yet, to have a spare copy while resize2fs-ing

mdadm --grow /dev/md1 --size=max

resize2fs /dev/md1

1. If the resize2fs-ing went OK, we can now add /dev/sdb3:

mdadm /dev/md1 --add /dev/sdb3
