Hello.
If i need to resize root partition on live file system i do
fdisk /dev/sda delete old partition table and write new. After that
fdisk say's that system use old partition table before reread it via
partprobe or something else.
But if i modify root partition partprobe say's that it is already in use
and i need to reboot system to see changes and do resize fs.
Is that possible to reread partition table for root fs without
rebooting? I ca'n use lvm on something else, i'm use plain ext3 fs.
P.S. This is need for xen domU, i see that in blkfront_connect function
this code:
/*
* Potentially, the back-end may be signalling
* a capacity change; update the capacity.
*/
err = xenbus_scanf(XBT_NIL, info->xbdev->otherend,
"sectors", "%Lu", §ors);
if (XENBUS_EXIST_ERR(err))
return;
printk(KERN_INFO "Setting capacity to %Lu\n",
sectors);
set_capacity(info->gd, sectors);
revalidate_disk(info->gd);
If i'm add after revalidate disk some function to reread partiotion
table does it can work?
Sorry for may be stupid question...
