After managing dozens of production servers, I've found that the classic "one root partition" approach often leads to operational headaches. Let me share a battle-tested partitioning scheme specifically optimized for LAMP environments with large file handling requirements.

While your proposed layout shows good intention, these issues stand out:

• Over-allocating to /tmp (800GB for PHP uploads is excessive)
• Underestimating MySQL's I/O patterns
• Missing critical partitions like /var/log

For a 2TB RAID1 LAMP server handling 2GB uploads:

# fdisk -l output example
Disk /dev/sda: 2 TiB, 2199023255552 bytes
/dev/sda1   /         50G   ext4
/dev/sda2   /var      800G  ext4   # Apache docroot
/dev/sda3   /var/lib/mysql  300G  xfs    # Database optimized
/dev/sda4   /tmp      200G  ext4   # PHP upload_tmp_dir
/dev/sda5   /home     50G   ext4
/dev/sda6   /var/log  20G   ext4   # Isolated logs
/dev/sda7   swap      4G    swap

Notice the XFS for MySQL - here's why:

# MySQL config snippet
[mysqld]
innodb_file_per_table=1
innodb_flush_method=O_DIRECT
innodb_io_capacity=2000
# Requires XFS for optimal performance

For the PHP upload requirement:

# php.ini adjustments
upload_max_filesize = 2G
post_max_size = 2.1G
memory_limit = 256M

# Systemd tmpfile.d config
# /etc/tmpfiles.d/php-uploads.conf
D /tmp/php_uploads 1770 www-data www-data 1d

For RAID1 arrays, consider these mount options:

# /etc/fstab example
/dev/md0  /var/lib/mysql  xfs  defaults,noatime,nodiratime,logbsize=256k 0 2
/dev/md1  /var/www        ext4 defaults,noatime,data=writeback,barrier=0 0 2

Set up these critical alerts:

• 90% full on /var/log
• IOwait > 20% on database partition
• inode usage > 80% on /tmp

When configuring a production server with a 2TB RAID 1 array for LAMP stack operations, the partitioning scheme must balance performance, security, and maintainability. The proposed layout shows good understanding of separation of concerns:

# Sample fdisk output showing partition structure
Disk /dev/sda: 2 TiB, 2199023255040 bytes
Device       Start        End    Sectors  Size Type
/dev/sda1     2048   2099199    2097152    1G Linux swap
/dev/sda2  2099200  211964927  209865728  100G Linux filesystem (/) 
/dev/sda3 211964928 2319649279 2107684352 1000G Linux filesystem (/var)
/dev/sda4 2319649280 4095999999 1776350720  800G Linux filesystem (/tmp)
/dev/sda5 4096000000 4194303999   98304000   96G Linux filesystem (/home)

/var Allocation: The 1TB allocation is justified for several reasons:

• MySQL databases (typically /var/lib/mysql)
• Apache logs (/var/log/apache2)
• Package manager cache (/var/cache/apt)
• Mail spool (/var/mail)

For MySQL optimization, consider adding this to /etc/fstab:

/dev/sda3 /var ext4 noatime,nodiratime,data=writeback,barrier=0 0 1

The 800GB /tmp partition addresses PHP file uploads through these php.ini settings:

upload_max_filesize = 2048M
post_max_size = 2056M 
upload_tmp_dir = /tmp/php_uploads

Create a dedicated tmpfs for session data:

tmpfs /tmp/php_sessions tmpfs defaults,noexec,nosuid,size=2G 0 0

For RAID 1 arrays, we can improve performance with these kernel parameters in /etc/sysctl.conf:

vm.swappiness = 10
vm.dirty_ratio = 15
vm.dirty_background_ratio = 5

Consider adding these mount options for the database partitions:

/dev/md0 /var/lib/mysql ext4 rw,noatime,nodiratime,data=writeback,stripe=256 0 2

For high-availability setups, consider:

1. Using LVM for flexible resizing
2. Separate /var/lib/mysql to dedicated partition
3. Implementing XFS for large file operations

Example LVM setup:

pvcreate /dev/sda2 /dev/sda3 /dev/sda4
vgcreate vg_server /dev/sda2 /dev/sda3 /dev/sda4
lvcreate -L 100G -n lv_root vg_server
lvcreate -L 1T -n lv_var vg_server
lvcreate -L 800G -n lv_tmp vg_server
