Hi Gull04,

Thank you for your answer.
Is "stripe size" the same as "chunk size"?

Apparently, mine is 512k:
Code:
cat /proc/mdstat

returns
Code:
Personalities : [raid0]
md0 : active raid0 sdd1[2] sdc1[1] sdb1[0]
      5860543488 blocks super 1.2 512k chunks

unused devices: <none>

How can I identify if this is the source of the problem?

Regards
Santiago

NAME
lvmdiskscan - scan for all disks / multiple devices / partitions available SYNOPSIS
lvmdiskscan [-d|--debug] [-h|--help] [-l|--lvmpartitions] [-v|--verbose] DESCRIPTION
To give an overview about online peripherals usable to LVM, lvmdiskscan scans all SCSI, (E)IDE disks, multiple, loop and network block devices in the system and lists them on standard output with name, size and type (text/hex). The size is the real device size, not the size stored in the VGDA (See pvcreate(8) ) for details. OPTIONS -d/--debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -l, --lvmpartition Gives an overview about all LVM system identified partitions only. -v, --verbose Gives verbose runtime information about lvmdiskscan's activities. DIAGNOSTICS
lvmdiskscan returns an exit code of 0, if disks / multiple devices / partitions where found and > 0 for error: 1 no special files found 2 no disks / multiple devices / disk partitions found 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line See also lvm(8), pvcreate(8), pvdisplay(8), pvscan(8) AUTHOR
