-======i-MSCP Requirements======
+====== System requirements ======
-=====General=====
+  * 1 GHz or faster 32 bits (x86) or 64 bits (x64) processor
-  * 1 GHz or faster 32 bits (x86) or 64 bits (x64) processor (recommended)
   * 1 Gio memory (minimum) - For heavily loaded servers or high flow is recommended at least 8 Gio
-  * 1 Gio of available hard disk space (only for i-MSCP and managed services
+  * 1 Gio of available hard disk space for i-MSCP and managed services, excluding user data
-  * Internet access (100 Mbits/s recommended)
+  * Internet access (at least 100 Mbits/s recommended)
-  * A file system that supports extended attributes such as ext2, ext3, ext4 or reiserfs*.
+  * A Linux kernel >= 2.6.26
+  * A file system supporting extended attributes such as ext2, ext3, ext4 or reiserfs*****
+  * Appropriate privileges to create devices (**CAP_MKNOD** capability)
+  * Appropriate privileges to mount, unmount and remount filesystems (**CAP_SYS_ADMIN** capability)
-* In case of reiserfs, you must ensure that your file system is mounted with the **attrs** option. See [[start:howto:reiserfs|Using reiserfs file system with i-MSCP]] for more information.
+===== Reiserfs users =====
-=====Distribution=====
+In order, to use the reiserfs file system with i-MSCP, you must follow these steps:
-  * Debian >= Wheezy (Base system with standard packages installed)
+Edit your **/etc/fstab** file to add the **attrs** option for your device (e.g. device containing the /var partition). For
-  * Ubuntu >= Precise Pangolin (Base system with standard packages installed)
+instance:
+    UUID=74699091-3ab8-43f2-bdd5-d1d898ab50fd /     reiserfs notail          0    1
+should be updated to:
+    UUID=74699091-3ab8-43f2-bdd5-d1d898ab50fd /     reiserfs notail,attrs    0    1
+Once you did that, you can remount your device. For instance:
+    mount -o remount /dev/disk/by-uuid/74699091-3ab8-43f2-bdd5-d1d898ab50fd
+If needed, you can find the uuid of your device, with the following command:
+    blkid <device>
+where **<device>** must be replaced by your device path such as **/dev/sda1**
-=====Software Version=====
+===== LXC containers =====
-  * PHP >= 5.3.2
+If you want install i-MSCP inside a LXC container, the following conditions have to be met:
-  * Perl >= 5.14.2
-=====Note for Proxmox/Docker/LXC users=====
+  * You must have the **CAP_MKNOD** capability inside the container. Thus, you must ensure that **mknod** is not in the list of dropped capabilities
+  * You must have the **CAP_SYS_ADMIN** capability inside the container (required to mount filesystems). Thus, you must ensure that `sys_admin` is not in the list of dropped capabilities.
+  * You must allow the creation of devices inside the container by white-listing them. Easy solution is to add **lxc.cgroup.devices.allow = a *:* rwm** in LXC container configuration file.
+  * If you use **Apparmor**, you must allow **mount**,**umount** and **remount** operations inside your container by modifying the default apparmor profile **/etc/apparmor.d/lxc/lxc-default** or by creating a specific apparmor profile for the container.
-If you want install i-MSCP inside a LXC container, the following conditions must be met:
+Note that these operations must be done on the host, not in the container.
-  - You must have the ''CAP_MKNOD'' capability inside the container. Thus, you must ensure that `mknod` is not in the list of dropped capabilities (needed for pbuilder).
-  - You must have the ''CAP_SYS_ADMIN'' capability inside the container (needed for mount(8)). Thus, you must ensure that `sys_admin` is not in the list of dropped capabilities.
-  - You must allow the creation of devices inside the container by white-listing them (needed for pbuilder). Easy solution is to add ''lxc.cgroup.devices.allow = a *:* rwm'' in LXC container configuration file.
-  - If you use ''Apparmor'', you must allow bindmounts inside your container by modifying the default apparmor profile ''/etc/apparmor.d/lxc/lxc-default'' or by creating a specific apparmor profile for the container.
-Note that all those operations must be done on the host, not in the container.

+===== OpenVZ containers (Proxmox and Virtuozzo) =====
+You could have to increase the **fs.ve-mount-nr** limit, else, an error such as **mount: Cannot allocate memory** could be threw by CageFS. To avoid this problem you must:
+  - Increase the limit by adding an entry such as **fs.ve-mount-nr = 4096** to your **/etc/sysctl.conf** file
+  - Make the new limit effective by executing the **sysctl -p** command

+Note that these operations must be done on the host, not in the container.
