Hi when I executed the lvdisplay command i get the following output --- Logical volume --- LV Name /dev/vg/lv1 VG Name vg LV Write Access read/write LV Status available LV # 1 # open 0 LV Size 4 GB Current LE 1024 Allocated LE 1024 Stripes 4 Stripe size (KByte) 16 Allocation next free Read ahead sectors 1024 Block device 58:0 Can any one tell me what that ALLOCATION next free means and also what strict allocation means. I also tried lvdisplay with -v option it gives me read and writes What that exactly means 1. No of read and write operation 2 No of blocks transferd 3. No of sectors read or written One more thing this io statics is from which time 1. bootup time 2. lv creation time Thanks Sachin. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
