Details

reserved-filesystem is the currently inactive rootfs partition or volume for some Dual-Boot models.
The currently active counterpart is the filesystem partition or volume.
On 63xx models this is called filesystem_reserved.

On non UBI Dual-Boot models filesystem and reserved-filesystem are logical names honoring the linux_fs_start variable:

7490 fw 7.29 - linux_fs_start = 0:

fritz3:/var/mod/root $ grep filesystem /proc/mtd

mtd1: 03000000 00020000 "filesystem"
mtd3: 03000000 00020000 "reserved-filesystem"
mtd5: 19600000 00020000 "nand-filesystem"

7490 fw 7.29 - linux_fs_start = 1:

fritz3:/var/mod/root $ grep filesystem /proc/mtd

mtd1: 03000000 00020000 "reserved-filesystem"
mtd3: 03000000 00020000 "filesystem"
mtd5: 19600000 00020000 "nand-filesystem"

On some CONFIG_UBI models this is the avm_filesys_0 or avm_filesys_1 volume.
Both get a device and are renamed before they get entries in /proc/mtd.

7530 fw 7.39:

root@fritz:/var/mod/root# grep filesystem /proc/mtd

mtd5: 02c14000 0001f000 "filesystem"
mtd6: 02c14000 0001f000 "reserved-filesystem"
mtd8: 00c79000 0001f000 "nand-filesystem"

root@fritz:/var/mod/root# ubinfo -a | grep filesys

Name:        avm_filesys_0
Name:        avm_filesys_1

root@fritz:/var/mod/root# blkid

/dev/ubi0_3: UUID="xxxx" TYPE="ubifs"
/dev/ubi0_1: TYPE="squashfs"
/dev/ubi0_0: TYPE="squashfs"
/dev/mtdblock4: UUID="xxxx" TYPE="ubi"
/dev/mtdblock5: TYPE="squashfs"
/dev/mtdblock6: TYPE="squashfs"

The devices always use the sequential UBI volume order, regardless of the linux_fs_start variable.
Just the mtd partition names are renamed different depending on this variable.

With linux_fs_start = 0:

mtd5: 02c14000 0001f000 "filesystem"
mtd6: 02c14000 0001f000 "reserved-filesystem"

With linux_fs_start = 1:

mtd5: 02c14000 0001f000 "reserved-filesystem"
mtd6: 02c14000 0001f000 "filesystem"

Dependencies

Daily updated index of all dependencies of this partition. Last update: GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Daily updated index of the presence, path and size of this partition for each model. Last update: 2024-11-23 06:56 GMT.
Showing all models using this partition. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
